&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;
&lt;br /&gt;

=== Passwordless Login ===&lt;br /&gt;
This example shows how to add a security key to the Microsoft account and how to log in to the account without a username and password.&lt;br /&gt;
&lt;br /&gt;
A passwordless login to the MS account was tested with the following in every possible combination (OS+Browser+Security Key):&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;

&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;

&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;
&lt;br /&gt;

=== Passwordless Login ===&lt;br /&gt;
This example shows how to add a security key to the Microsoft account and how to log in to the account without a username and password.&lt;br /&gt;
&lt;br /&gt;
A passwordless login to the MS account was tested with the following in every possible combination (OS+Browser+Security Key):&lt;br /&gt;
&lt;br /&gt;

&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;

&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator.

After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;

&lt;div&gt;[[File:webauthn_logo.PNG|500px|thumb|WebAuthn logo]]&lt;br /&gt;
&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;
&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;[[File:webauthn_logo.PNG|500px|thumb|WebAuthn logo]]&lt;br /&gt;
&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;
&lt;br /&gt;

Try it yourself if you want to! &lt;br /&gt;

&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;

== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;

&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;
&lt;br /&gt;

=== Passwordless Login ===&lt;br /&gt;
This example shows how to add a security key to the Microsoft account and how to log in to the account without a username and password.&lt;br /&gt;
&lt;br /&gt;
A passwordless login to the MS account was tested with the following in every possible combination (OS+Browser+Security Key):&lt;br /&gt;

&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;

=== Passwordless Login ===&lt;br /&gt;
This example shows how to add a security key to the Microsoft account and how to log in to the account without a username and password.&lt;br /&gt;
&lt;br /&gt;
The following was used for this example:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Security Key:&#039;&#039;&#039; [[Yubico Security Key]], [[Yubikey 5 C]], [[Yubikey 5 NFC]], [https://www.yubico.com/at/product/yubikey-5c-nfc/ Yubikey 5C NFC]&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Operating System&#039;&#039;&#039;: Windows 10&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Browser:&#039;&#039;&#039; Google Chrome, Mozilla Firefox, Microsoft Edge, Opera&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Assumption: one has a Microsoft account but has not yet added a security key&lt;br /&gt;
&lt;br /&gt;
1. Sign in with username and password&lt;br /&gt;
&lt;br /&gt;
2. Go to &#039;&#039;&#039;&#039;&#039;Security&amp;gt;Advanced Security Options&#039;&#039;&#039;&#039;&#039;&lt;br /&gt;

&amp;lt;br /&amp;gt;&lt;br /&gt;
4. A window shows the additional options to verify or sign in. Select &#039;&#039;&#039;&#039;&#039;Use a security key&#039;&#039;&#039;&#039;&#039;&lt;br /&gt;
[[File:FIDO2-WebAuthn_pwless_2.PNG|none|300px]]&lt;br /&gt;
&amp;lt;br /&amp;gt;&lt;br /&gt;
5. Read the instruction for your prefered method (USB or NFC) to register the security key. In this example USB was chosen.&lt;br /&gt;

&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;

&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
:The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
:The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
:The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
=== Passwordless Login ===&lt;br /&gt;
This example shows how to add a security key to the Microsoft account and how to log in to the account without a username and password.&lt;br /&gt;
&lt;br /&gt;
The following was used for this example:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Security Key:&#039;&#039;&#039; &lt;br /&gt;

&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
:The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
:The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
:The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;

&lt;br /&gt;
=== Passwordless Login ===&lt;br /&gt;
This example shows how to add a security key to the Microsoft account and how to log in to the account without a username and password.&lt;br /&gt;
&lt;br /&gt;
The following was used for this example:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Security Key:&#039;&#039;&#039; &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Operating System&#039;&#039;&#039;: Windows 10&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Browser:&#039;&#039;&#039; Google Chrome, Mozilla Firefox, Microsoft Edge, Opera&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Assumption: one has a Microsoft account but has not yet added a security key&lt;br /&gt;
&lt;br /&gt;
1. Sign in with username and password&lt;br /&gt;
2. Go to &#039;&#039;&#039;&#039;&#039;Security&amp;gt;Advanced Security Options&#039;&#039;&#039;&#039;&#039;&lt;br /&gt;

[[File:FIDO2-WebAuthn_pwless_2.PNG|none|300px]]&lt;br /&gt;
&lt;br /&gt;
5. Read the instruction for your prefered method (USB or NFC) to register the security key. In this example USB was chosen.&lt;br /&gt;
[[File:FIDO2-WebAuthn_pwless_3.PNG|none|600px]]&lt;br /&gt;
&lt;br /&gt;
6. Touch the button of your security key &lt;br /&gt;

&lt;br /&gt;
;&#039;&#039;&#039; Authenticator &#039;&#039;&#039;&lt;br /&gt;
:The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
:The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
;&#039;&#039;&#039;Relying Party (RP)&#039;&#039;&#039;&lt;br /&gt;
:The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
=== Passwordless Login ===&lt;br /&gt;
This example shows how to add a security key to the Microsoft account and how to log in to the account without a username and password.&lt;br /&gt;
&lt;br /&gt;
The following was used for this example:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Security Key:&#039;&#039;&#039; &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Operating System&#039;&#039;&#039;: Windows 10&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Browser:&#039;&#039;&#039; Google Chrome, Mozilla Firefox, Microsoft Edge, Opera&lt;br /&gt;
&lt;br /&gt;
Assuming one has a Microsoft account but has not yet added a security key&lt;br /&gt;
&lt;br /&gt;
# Sign in with username and password&lt;br /&gt;
# Go to &#039;&#039;&#039;&#039;&#039;Security&amp;gt;Advanced Security Options&#039;&#039;&#039;&#039;&#039;&lt;br /&gt;
# Click on &#039;&#039;&#039;&#039;&#039;Add a new way to sign in or verify&#039;&#039;&#039;&#039;&#039;&lt;br /&gt;

&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;

&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
=== Client/Platform ===&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
=== Relying Party (RP) ===&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the FIDO2-authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
=== Login WebAuthn test website ===&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;

== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;

WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;

&lt;br /&gt;
=== Authenticator ===&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
=== Client/Platform ===&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
=== Relying Party (RP) ===&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the FIDO2-authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;

&lt;div&gt;[[File:webauthn_logo.PNG|500px|thumb|WebAuthn logo]]&lt;br /&gt;
&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
=== Authenticator ===&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
*external authenticator (e.g. security key) that is removable from the device &lt;br /&gt;
*internal authenticator (e.g. fingerprint reader) that is implemented on the device and is not removeable&lt;br /&gt;
&lt;br /&gt;
=== Client/Platform ===&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser for web applications or an operating system subsystem that offers a platform-specific FIDO API for mobile or desktop apps.&lt;br /&gt;
&lt;br /&gt;
=== Relying Party (RP) ===&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the FIDO2-authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;

&#039;&#039;&#039;Platform Authenticator:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The platform Authenticator is implemented on a device thus using a client device-specific transport called platform attachment. This authenticator is usually not removable from the device and the credential created with it is called platform credential.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Roaming Authenticator:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
A roaming Authenticator is attached using cross-platform transport and is thus called a cross-platform attachment. They are removable from the device, such as an USB key fob, and the generated credential is called roaming credential&lt;br /&gt;

&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture&amp;lt;ref name=&amp;quot;overview&amp;quot; /&amp;gt;]]&lt;br /&gt;
&lt;br /&gt;
=== Authenticator ===&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication, and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
external authenticator e.g. security key&lt;br /&gt;
internal authenticator e.g. fingerprint reader&lt;br /&gt;
&lt;br /&gt;
=== Client/Platform ===&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API, and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser that reveal the WebAuthn API to the web applications or &lt;br /&gt;
&lt;br /&gt;
=== Relying Party (RP) ===&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the FIDO2-authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Authenticators ==&lt;br /&gt;
&lt;br /&gt;
The authenticator is necessary to create a public key credential and to register with a Relying Party. &lt;br /&gt;
There are two types of Authenticators:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Platform Authenticator:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The platform Authenticator is implemented on a device thus using a client device-specific transport called platform attachment. This authenticator is usually not removable from the device and the credential created with it is called platform credential.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Roaming Authenticator:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
A roaming Authenticator is attached using cross-platform transport and is thus called a cross-platform attachment. They are removable from the device, such as an USB key fob, and the generated credential is called roaming credential&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture &amp;lt;ref name=&amp;quot;yubicooverview&amp;quot; /&amp;gt; == &lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|600px|FIDO2/WebAuthn Architecture[https://developers.yubico.com/WebAuthn/WebAuthn_Developer_Guide/Overview.html]]]&lt;br /&gt;
&lt;br /&gt;
=== Authenticator ===&lt;br /&gt;
The authenticator creates credentials, generates cryptographic proof of user authentication, and administrate the PIN.&lt;br /&gt;
&lt;br /&gt;
There are two types of authenticators:&lt;br /&gt;
&lt;br /&gt;
external authenticator e.g. security key&lt;br /&gt;
internal authenticator e.g. fingerprint reader&lt;br /&gt;
&lt;br /&gt;
=== Client/Platform ===&lt;br /&gt;
The client implements CTAP2 and client-side WebAuthn API, and proves the validity of the identity of the Relying Party to prevent phishing attacks. &lt;br /&gt;
The client could be a browser that reveal the WebAuthn API to the web applications or &lt;br /&gt;
&lt;br /&gt;
=== Relying Party (RP) ===&lt;br /&gt;
The Relying Party consists of at least one webserver, the server-side parts of the WebAuthn API and a WebAuthn Server, that has a trust store.&lt;br /&gt;
The trust store contains the public trust parts for the attestation of the FIDO2-authenticator.&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Authenticators ==&lt;br /&gt;
&lt;br /&gt;
The authenticator is necessary to create a public key credential and to register with a Relying Party. &lt;br /&gt;
There are two types of Authenticators:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Platform Authenticator:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The platform Authenticator is implemented on a device thus using a client device-specific transport called platform attachment. This authenticator is usually not removable from the device and the credential created with it is called platform credential.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Roaming Authenticator:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
A roaming Authenticator is attached using cross-platform transport and is thus called a cross-platform attachment. They are removable from the device, such as an USB key fob, and the generated credential is called roaming credential&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;

&lt;br /&gt;
== Summary == &lt;br /&gt;
&lt;br /&gt;
WebAuthn is an Application created by the FIDO (Fast Identity Online) alliance and the W3C (World Wide Web Consortium) to offer the possibility of passwordless authentication online. The latest recommendation is of March 2019 published by the W3C. Instead WebAuthn work either with the inbuild Authenticator of the device, such as fingerprint sensor or facial recognition, or with an extern media like an USB Stick for verification. &lt;br /&gt;
&lt;br /&gt;
== Goal ==&lt;br /&gt;
Its purpose is to offer a more secure and easy possibility to log into your online accounts without storing or remembering huge amounts of passwords to prevent the possibility of passwords getting leaked or forgotten. &lt;br /&gt;
&lt;br /&gt;
== Architecture ==&lt;br /&gt;
&lt;br /&gt;
[[File:FIDO2-WebAuthn_Architecture.PNG|thumb|700px|FIDO2/WebAuthn Architecture[https://developers.yubico.com/WebAuthn/WebAuthn_Developer_Guide/Overview.html]]]&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Authenticators&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Client/Platform&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Relying Party&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
== Functionality ==&lt;br /&gt;
WebAuthn works with two ceremonies:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Registration:&#039;&#039;&#039;&lt;br /&gt;
The Registration involves a Relying Party, the server that hosts the Website, and the user client that must host at least one authenticator. To register, the user has to navigate to the website where he wishes to use Web Authentication and sign in using the method that was used to this point, which means for example a password. After that it is to choose to register this site from now an using Web Authentication, which leads to the request to submit the configures authorization gesture. When the provided gesture is accepted, the registrations is complete.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;The Authentication:&#039;&#039;&#039;&lt;br /&gt;
For the user, the authentication using the Web Authenticator works seemingly as a normal login with just the difference that instead of typing a password to verify its identity, the user uses the same Authentication gesture that he used to register to the site.&lt;br /&gt;
&lt;br /&gt;
== Authenticators ==&lt;br /&gt;
&lt;br /&gt;
The authenticator is necessary to create a public key credential and to register with a Relying Party. &lt;br /&gt;
There are two types of Authenticators:&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Platform Authenticator:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The platform Authenticator is implemented on a device thus using a client device-specific transport called platform attachment. This authenticator is usually not removable from the device and the credential created with it is called platform credential.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Roaming Authenticator:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
A roaming Authenticator is attached using cross-platform transport and is thus called a cross-platform attachment. They are removable from the device, such as an USB key fob, and the generated credential is called roaming credential&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn_1.PNG|400px]]&lt;br /&gt;
&lt;br /&gt;
First you have to navigate to the Website where you want to change the default login to WebAuthn, in this case it is the test website of WebAuthn, the link is provided below, so we create a new user and pick the option PMT for we are going to use the inbuilt fingerprint sensor of the laptop to verify our identity. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn2.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
The security feature now asks us to verify the identity with the same Authenticatior you want to use every time you log into the website. The choice will be stored with your ID and used every time you login.&lt;br /&gt;
&lt;br /&gt;
[[File:webauthn3.PNG|600px]]&lt;br /&gt;
&lt;br /&gt;
The login was a scucess and now we are able to login just using our fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn4.PNG|300px]]&lt;br /&gt;
&lt;br /&gt;
You are ask to provide the same authentication which you used to login, in this case the fingerprint. &lt;br /&gt;
&lt;br /&gt;
[[File:webauthn5.PNG|800px]]&lt;br /&gt;
&lt;br /&gt;
If everything goes well, you are now logged in just using a fingerprint sensor!&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
Try it yourself if you want to! &lt;br /&gt;
