Why FIDO2?

FIDO2 is an open authentication standard that consists of W3C (World Wide Web Consortium) WebAuthn API (Web Authentication specification) and the CTAP (Client To Authenticator Protocol). WebAuthn has been implemented by the major browsers, and CTAP2 is supported by hardware and platform companies. FIDO2 cryptographic login credentials are unique across every website, biometrics or other secrets like passwords never leave the user's device and are never stored on a server.
