Authentication Methods
Fast IDentity Online (FIDO)
SurePassID Universal MFA is a certified universal server for FIDO UAF, U2F, and FIDO2 authentication.

Compliant, passwordless MFA that supports biometric authentication
Based on open standards from the FIDO Alliance, Fast IDentity Online (FIDO) UAF, U2F, and FIDO2 authentication enables password-only logins to be replaced with secure and fast login experiences across websites and apps.

Universal Second Factor (U2F) – User inserts a U2F universal serial bus (USB) token into any port. Then the user presses the U2F token button to authenticate whenever logging in to a U2F or FIDO2-enabled website or app.

Universal Authentication Framework (U2F) – User chooses a biometric authentication method for their device and uses it to authenticate whenever logging in to a UAF or FIDO2-enabled website or app.

FIDO2 – User chooses a biometric or FIDO Security Key authentication method and uses it to authenticate to any FIDO2-enabled website or app.
