On my Samsung Galaxy A14, I could configure my fingerprint for use within apps (such as banking and qualified electronic signature apps) but not for unlocking my phone. This is my preferred setup as I do not want to be able to unlock my phone solely with a fingerprint.

However, on my new Fairphone 4, which runs a closer-to-stock version of Android 13, I can't seem to locate an option for this. Surely, there must be a way to achieve this, somehow?

As a permanent workaround, 3rd-party apps can "disable" fingerprint unlock by force-locking the system and requiring strong authentication (PIN, pattern, or password) to unlock the device. Note that this requires the app to be registered as a device administrator to leverage the feature.

  1. Tasker

    • Profile: Event - Display - Display Off
    • Task: Display - System Lock
  2. Automate

    1. Add new block: Interface - Display on?
    2. Connect Flow beginning (GO) to When display on (IN)
    3. Connect When display on (YES) to When display on (IN)
    4. Add new block: Interface - Device lock
    5. Connect When display on (NO) to Lock device (IN)
    6. Connect Lock device (OK) to When display on (IN)
  • Thanks! Works like charm. Now that you mention it, I vaguely remember having a similar setup on one of my even older phones.

There's an old Android Device Admin API for disabling fingerprints on the lockscreen, which, while deprecated, continues working even on Android 14 as long as the app accessing that API targets at most API28.

Somebody wrote an app for toggling that API and it's available on F-Droid.


On stock Android (AOSP), it doesn't seem to be possible to customize how fingerprints should be used, other than the default for unlocking the device and additionally for biometric authentication.

A YouTube video by the official Fairphone channel shows that the interface is the same as AOSP, where there is no customization other than adding, removing, or renaming the fingerprints. (Cross-checked with Google Pixel 3a on stock Android 12; additional reference).

For these devices, the standard way to disable fingerprint unlock is to delete all the fingerprints. For temporary workaround, activate Lockdown mode if available, but this always needs to be re-activate on each unlock.

As for Samsung devices, they actually made customization to the Android OS to add the "Fingerprint unlock" toggle and other settings. (Confirmed on Galaxy M12, Android 13).
