You can enroll up to five different fingerprints to use with TouchID. By default, iOS labels each one sequentially (e.g., Finger 1, Finger 2). Instead, you can set a custom name to better identify which finger each fingerprint corresponds to.

  • Open Settings
  • Tap Touch ID & Passcode
  • Tap a fingerprint to rename it

touchid-rename

If you’ve added more than one fingerprint and don’t know which fingers they correspond to, touch the Home button while in the Touch ID settings. The corresponding fingerprint will be highlighted for you to identify.

Touch ID fingerprints are not limited to your own. If you’re using a shared device (e.g., family iPad) or perhaps want your spouse to have access to your device in case of emergency, you can add—and then label—other people’s fingerprints.
