Overview
Microsoft Authenticator may ask you to verify your identity using Face ID, fingerprint recognition, or your device PIN when opening the app or approving a multifactor authentication (MFA) request.
This additional verification is controlled by the App Lock setting in Microsoft Authenticator. If you receive an extra biometric or PIN prompt during MFA, you can turn off App Lock to remove that additional prompt.
Applies To
Users: DSU students, faculty, and staff
Devices: Android phones and Apple iPhones
Application: Microsoft Authenticator
Before You Begin
Make sure Microsoft Authenticator is installed and configured on your phone.
Important: Turning off App Lock does not disable MFA or remove Face ID, fingerprint recognition, or your device PIN from your phone. It only disables the additional App Lock verification inside Microsoft Authenticator.

- Go to your iPhone's Home Screen.
- Press and hold the Microsoft Authenticator app icon.
- Look for the option Don't Require Face ID.
Note: If you see Don't Require Face ID, the iPhone-level app lock is enabled and may be responsible for the additional Face ID prompt.
