You are required to set a passcode that must be entered each time you turn on or wake up iPad.
Set, change, or turn off the passcode. Go to Settings > Touch ID & Passcode.
To adjust when iPad automatically locks (and then requires the passcode to unlock), go to Settings > Display & Brightness > Auto-Lock.
Setting a passcode turns on data protection, using your passcode as a key to encrypt Mail messages and attachments stored on iPad, using 256-bit AES encryption. (Other apps may also use data protection.)
Increase security. Turn off Simple Passcode and use a longer passcode. To enter a passcode that’s a combination of numbers and letters, you use the keyboard. If you prefer to unlock iPad using the numeric keypad, set up a longer passcode using numbers only.
When you set up Touch ID, you can unlock iPad by placing a finger on the Home button. Developers can also allow you to use Touch ID to sign in to their apps.
To use Touch ID, you must set a passcode on your iPad. You must enter your passcode for additional security validation when you do the following:
- Turn on or restart your device
- View or change passcode settings
Set up fingerprint recognition. Go to Settings > Touch ID & Passcode. Tap Add a Fingerprint, then follow the onscreen instructions. You can add multiple fingerprints (both of your thumbs and forefingers, for example).
Name a fingerprint. Tap the fingerprint, then enter a name, such as “Thumb.”
Delete a fingerprint. Tap the fingerprint, then tap Delete Fingerprint. If you added more than one fingerprint, place a finger on the Home button to find out which fingerprint it is.
Turn off Touch ID. Go to Settings > Touch ID & Passcode, then turn off one or more options: iPad Unlock, Apple Pay, or iTunes & App Store.
