Did you know you can give you stored Touch ID fingerprints names? This can be helpful to keep track of which fingerprints have been assigned to which slots — especially useful as well if you’ve temporarily added somebody else’s fingerprint and want to keep track of it, or even if you just need to know which finger to delete so you can re-train it.
While Touch ID doesn’t really give you a way to do this while adding fingerprints, you can do it later simply by going into Settings, Touch ID & Passcode and then tapping on the fingerprint you want to assign a name to.
Type in your name, tap “Back” and you’re done.
On the other hand, if you want to simply delete the fingerprint entirely instead, you can just tap the “Delete Fingerprint” button that appears below the name field.
