Touch ID makes it easy to register your fingerprints so you can unlock your iPhone 5s or make iTunes purchases without a passcode or password. Once you've registered a few, however, the default labels Touch ID assigns them are pretty much useless when it comes to figuring out which is which. That's especially true if you've registered a family member's fingerprint so they can share your iPhone. Luckily Apple does let you rename Touch ID fingerprint labels to make them much easier to keep track of and trouble shoot later!
How to re-name a Touch ID fingerprint
- Launch the Settings app.
- Scroll down and tap on Touch ID & Passcode.
- Type in your passcode when asked.
- Rest a finger on the Touch ID sensor (Home button)
- When the corresponding label for that finger turns gray, tap on the > button to the right of the label.
- Type in a new, more recognizable name for your fingerprint. (i.e. right thumb.)
Repeat the steps 4-6 until all your fingerprints are labeled.
Now, if you ever want to see if a specific finger is registered, re-register or delete your or someone else's finger, you can do so quickly and easily! You can also use those steps to better train Touch ID:
