Ipad Mini 6 Review Touch IdSource: Adam Oram / iMore

Many Apple devices now use Face ID for authentication purposes — but not all of them. There are still several of the best iPhones, iPads, and Macs that use Touch ID. Here's what you need to know about the authentication feature.

How to set up Touch ID on iPhone and iPad

You can register a fingerprint for Touch ID as part of the initial setup process on any new or restored iPhone or iPad. You can also set it up or add additional fingers at any time. The steps work on the best iPhone and best iPad models that support Touch ID.

  1. Launch the Settings app from your Home screen.
  2. Tap on Touch ID & Passcode.
  3. Type in your passcode for authorization, if asked (Touch ID requires a passcode, so if you don't have one already, you'll be asked to create one).

  4. Tap on the Add a Fingerprint button.

  5. Place the finger you want to register on the Home button and leave it there until you feel a buzz. If you're on the 2020 iPad Air, place your finger on the Power button.
  6. Lift your finger and place it back down. Repeat each time you feel a buzz.
  7. Tap continue when Touch ID alerts you that it has completed the first step and now requires peripheral data.
  8. Place the edges of the finger you want to register on the Home button or the Power button and leave it there until you feel a buzz.
  9. Lift your finger and place it back down. Repeat with a different edge until you've registered the entire surface of your finger.
  10. Tap Continue to finish.

Repeat for every other finger you want to add, up to five total. You can register any combination of your and other people's fingerprints, including family or staff. You can even temporarily register a travel-mate just in case of emergencies, without having to give them your passcode or password.

How to identify a Touch ID fingerprint

If you registered a fingerprint with Touch ID but don't remember which one is which — i.e., is Fingerprint 1 your right thumb or left index finger? — you can check and find out. That's how you can make sure you rename and delete the right ones in the future.

  1. Launch the Settings app.
  2. Tap on Touch ID & Passcode.
  3. Type in your passcode when asked.
  4. Scroll down to the Fingerprints section.
  5. Place your registered fingerprint on the Home button or the Power button.
  6. Look for the label that changes color from white to gray.

  2. Tap on Touch ID & Passcode.
  3. Type in your passcode when asked.

Repeat steps 4-6 until all your fingerprints are labeled.

How to turn off Touch ID for the Lock screen, Apple Pay, or the iTunes and App Stores

Touch ID is meant as a convenience. If you prefer more security on your Lock screen, like a strong alphanumeric password, you can turn Touch ID off.

  1. Launch the Settings app from your Home screen.
  2. Tap on Touch ID & Passcode.
  3. Enter your passcode when prompted.
  4. Switch iPhone/iPad Unlock, iTunes and App Store, Apple Pay, or Password AutoFill to Off.

How to delete a Touch ID fingerprint

If you have given someone fingerprint access to your device for an emergency or another reason and you don't need that person to have access anymore, it's a good idea to delete their fingerprint. Also, if a fingerprint becomes glitchy, you can remove it and redo it. That's because deleting Touch ID fingerprints is even easier than adding them!

  1. Launch the Settings app on your Touch ID-capable device.
  2. Tap on Touch ID & Passcode.
  3. Type in your passcode when prompted.
  4. Tap on the fingerprint you want to delete.
  5. Tap on Delete Fingerprint.
  6. Tap on the Touch ID & Passcode on the top right corner to go back.
