If you have an iPad Air 2 or an iPad mini 3, you can protect your tablet using Touch ID, the fingerprint sensor built into the Home button. By teaching the device your unique fingerprint, you can unlock your tablet by leaving your finger or thumb resting on the Home button. Here’s how to set up Touch ID:

  1. On the Home screen, tap Settings. The Settings app appears.

  2. Tap Touch ID & Passcode and then type your passcode (if you have one).

  3. Tap Add a Fingerprint. The Touch ID screen appears.

  4. Lightly rest your thumb — or whatever finger you most often use to press the Home button when you’re unlocking your iPad — on the Home button.

  5. Repeatedly lift and place your finger as Touch ID learns your fingerprint pattern.

  6. When you see the Adjust Your Grip screen, tap Continue.

  7. Once again, repeatedly lift and place your finger, this time emphasizing the edges of the finger.

  8. When you see the Complete screen, tap Continue.

  9. To specify another fingerprint, repeat Steps 3–8.

Here’s how you use Touch ID:

  • Unlock your iPad. Use your fingerprint-scanned finger to tap the Home button to wake the tablet, then leave the same finger resting on the Home button until the Home screen appears.

  • Make an iTunes purchase. In the iTunes Store, the App Store, or the iBooks Store, tap the price of the item and then tap the Buy button. When the Touch ID dialog appears, rest your finger on the Home button until the purchase is approved.

  • Make an in-app purchase. For apps that support Apple Pay, tap the Apple Pay button in the checkout screen then place your scanned finger over the Home button.

  • Make an Apple Pay purchase. You can use Touch ID to pay for goods in the real world without having to use cash or a credit card. In a merchant that accepts Apple Pay, place your scanned finger over the Home button, then hold the iPhone near the store’s contactless reader.
