FIDO2 WebAuthn is an open standard for strong authentication that enables users to securely log into websites and applications using biometric data, such as fingerprints or facial recognition, or hardware tokens like USB keys. It is designed to replace traditional password-based authentication methods, which are often vulnerable to phishing, keylogging, and other forms of cyber attacks.

WebAuthn, which stands for Web Authentication, is a part of the FIDO2 (Fast Identity Online 2) project, which is an initiative by the FIDO Alliance, a consortium of technology companies. The FIDO2 project aims to provide a secure and user-friendly authentication experience for users and developers alike.

WebAuthn works by using public-key cryptography to generate a unique key pair for each user and website combination. The public key is stored on the user's device, while the private key is kept secure and is never transmitted over the internet. When a user attempts to log into a website, the website sends a challenge to the user's device, which then uses the private key to generate a digital signature that is sent back to the website. The website can then verify the signature using the public key to authenticate the user.

One of the key benefits of WebAuthn is that it eliminates the need for passwords, which are often difficult to remember and can be easily compromised. Instead, users can use biometric data or hardware tokens to authenticate themselves, which are much more secure and convenient. Additionally, WebAuthn is designed to be resistant to phishing attacks, as the authentication process is tied to the specific website and user device combination.

WebAuthn is supported by a wide range of browsers, including Chrome, Firefox, Edge, and Safari, as well as many mobile operating systems, such as Android and iOS. It is also supported by a growing number of websites and applications, including major services like Google, Microsoft, and Dropbox.

In summary, FIDO2 WebAuthn is a secure and user-friendly authentication standard that uses public-key cryptography to enable users to log into websites and applications using biometric data or hardware tokens. It is designed to replace traditional password-based authentication methods and is supported by a wide range of browsers and operating systems.
