FIDO2

Overview[1][2]#

FIDO2 is a FIDO framework of specifications designed for Passwordless Authentication with credentials that cannot be phished, replayed, or breached when servers are compromised – and to do that without sacrificing user convenience across difference types of devices and clients.

To activate a FIDO2 credential (e.g., on a security key) users can employ gestures such as the use of PINs, biometrics, or button-pushing. Once the user is authenticated, the specifications enable the authenticator device (which could also be a host computer in its own right) to communicate information about the authentication event to other devices or systems using challenge/response protocols based on Asymmetric Key Cryptography.
