FIDO2 authentication while logging in a Dropbox account

FIDO2 is a joint initiative of FIDO alliance and World Wide Web Consortium’s (W3C). Expanding on Universal Authentication Framework (UAF) and Universal Second Factor (U2F), FIDO2 aspires to enable access to online services completely without the need of user-generated passwords.

FIDO2 incorporates the Web Authentication (WebAuthn) and Client-to-Authenticator Protocol (CTAP) specifications to enable secure login authentification.

In our ecosystem, FIDO2 has been first implemented in Trezor Model T firmware 2.1.6.
