Feature Request - Disable fingerprint unlock and retain it for apps
Summary
It would be nice to have fingerprint biometrics disabled at login, so it is PIN only whilst keeping fingerprints available to log in to apps.
Description
As a user I would like this because it means that PIN access is maintained, which is more secure whilst still allowing you rapid and secure access to apps which behave more smoothly with biometric log in.
Example 1: Log in to phone with the scrambled PIN layout. Once logged in, can access the banking app by fingerprint.
Added bonus is that it applies a barrier to unlocking and using the phone when one shouldn't, like driving.
This was possible in CalyxOS and AOSP: https://gitlab.com/CalyxOS/calyxos/-/issues/1165, https://review.calyxos.org/c/CalyxOS/platform_packages_apps_Settings/+/13284
