Problem statement

After disabling the MFA factor WebAuthn with FIDO Device Biometrics, logins have started to fail. In the dashboard logs the ‘failed login’ logs have the following error message:

"Webauthn with device biometrics required but not enabled as factor"

Cause

This can occur if Webauthn has been disabled in the MFA settings; however, the setting for the Authentication Profile is still set to ‘Identifier First + Biometrics’.

The Authentication Profile section is located by navigating to the Auth0 Dashboard > Authentication > Authentication Profile.

Solution

Depending on the use case, either re-enable Webauthn in the MFA settings or choose a different option for the Authentication Profile that does not expect device biometrics.
