Set up Touch ID on iPad
On an iPad with a Home button, iPad (10th generation), iPad Air (4th generation and later), or iPad mini (6th generation), you can use Touch ID to securely and conveniently unlock iPad, authorize purchases and payments, and sign in to many third-party apps.
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 App Store, Apple Books, or the iTunes Store. 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, do one of the following to identify its print:
On an iPad with a Home button: Rest a finger on the Home button.
On iPad (10th generation), iPad mini (6th generation), and iPad Air (4th generation and later): Rest a finger on the top button.
Tap the fingerprint, then enter a name (such as “Thumb”) or tap Delete Fingerprint.
Turn off Touch ID
Go to Settings > Touch ID & Passcode, then turn off one or more of the options.
