Set up Touch ID on iPad
Use Touch ID (supported models) to unlock iPad, authorize purchases and payments, and sign in to many third-party apps by pressing the Home button with your finger or thumb.
To use Touch ID, you must set a passcode on your iPad.
Turn on fingerprint recognition
If you didn’t turn on fingerprint recognition when you first set up your iPad, go to Settings
> Touch ID & Passcode.
Turn on any of the options, then follow the onscreen instructions.
If you turn on iTunes & App Store, you’re asked for your Apple ID password when you make your first purchase from the iTunes Store, the App Store, or Apple Books. When you make your next purchases, you’re asked to use Touch ID.
Note: If you can’t add a fingerprint or unlock your iPad using Touch ID, see the Apple Support article If Touch ID isn’t working.
Add a fingerprint
You can add multiple fingerprints (both of your thumbs and forefingers, for example).
Go to Settings
> Touch ID & Passcode.
Tap Add a Fingerprint.
Follow the onscreen instructions.
Name or delete a fingerprint
Go to Settings
> Touch ID & Passcode.
If you added more than one fingerprint, place a finger on the Home button to identify its print.
Tap the fingerprint, then enter a name (such as “Thumb”) or tap Delete Fingerprint.
Unlock iPad by touching instead of pressing the Home button
Go to Settings > Accessibility > Home Button, then turn on Rest Finger to Open.
Turn off Touch ID
Go to Settings > Touch ID & Passcode, then turn off one or more of the options.
