Interfaces and Applications


Like all other YubiKeys, the YubiKey Bio Series are USB 2.0 devices.


Developers: The USB PID and iProduct string are 0x0402 and YubiKey FIDO respectively (see YubiKey USB ID Values).


All keys in the YubiKey Bio Series support WebAuthn sites and applications that support the FIDO2 and FIDO U2F protocols (for more information, see YubiKey Bio and FIDO2 and YubiKey Bio and FIDO U2F). FIDO2 (also sometimes referred to as WebAuthn) is also the standard that enables the replacement of password-based authentication.

Each application can be enabled and disabled independently. Up to five fingerprints can be stored on a YubiKey Bio. For management, see Tools.
