Hello! I am on Android and I used to use my fingerprint as a biometric for Microsoft Authenticator. I no longer wish to do so, since I turned fingerprints on/off on the phone unlock itself, so I was wondering if there was a way to remove the option to use a fingerprint from Microsoft Authenticator in any way. Thank you in advance.

Yes. In Microsoft Authenticator, fingerprint use is controlled by App Lock.

  • Open Microsoft Authenticator.
  • Go to Settings.
  • Turn App Lock Off.

When App Lock is enabled, Authenticator asks for the device PIN or biometric each time the app is opened, and also when approving sign-in notifications. If biometric unlock is not available or fails, Authenticator can prompt for the PIN instead.

On Android work profiles, biometric settings may also need to be configured separately inside the work profile. Biometrics set for the regular device profile do not always carry over to the work profile.
