For my Photo Vault or AppLock, it would be nice to only allow one fingerprint instead of them all. Like, during setup you could ask a user to select a fingerprint from the list of registered ones or allow them to use all of them. This would allow for enhanced security and say for some reason you give fingerprint access to your friends, you could allow for only your fingerprint to unlock apps and view the photos in your vault.
Hi, thanks for your suggestion, it has been forwarded to the team.
