If you recently upgraded your phone to Android 13, then you may be encountering the consequences of a Google decision to downgrade the security rating of the FP3’s fingerprint sensor.

FP3 Android 13 - no fingerprint for 1Password any more

To my knowledge this is due to hightened security requirements by Google in Android 13 wrt. 11 which means the fingerprint hardware in the FP3 is no longer seen as “secure enough” by Google for the highest level of access to certain Android APIs including unlocking the Android keystore. As Fairphone has to pass Google certification there is no way to “cheat” around this. Maybe custom ROMs can. Edit: here are some techy details https://source.android.com/docs/security/features/biometric

You may be interested by this topic which suggests a solution for working around the problem.

FP3(+) Android 13 Fingerprint Sensor Workaround with Keepass2Android?

Just to mention … an already existing workaround is to use LineageOS instead of Fairphone OS (even if perhaps undesirable, a workaround is a workaround). LineageOS isn’t Google certified and took the resulting liberty to not adopt Google’s change regarding the fingerprint scanner.
