Changing the database of fingerprints can, if the app is properly configured, erase any “unlock token” stored on the phone.
I just tested this with KeepassDX on android. I deleted and re-added a fingerprint, the database that I had a fingerprint setup had relocked itself requiring the full password to be typed.
Nothing stopping an exta fingerprint being registered though…

Interesting, didn’t know that. Do you think that different enough from a timeout / reboot requirement of code? Could the app tell?
