You can lock iPad by putting it to sleep when you’re not using it. When you lock iPad, nothing happens if you touch the screen, but music continues playing and you can use the volume button.
- Lock iPad: Press the Sleep/Wake button.
- Unlock iPad: Press the Home button or the Sleep/Wake button, then drag the slider.
- Turn iPad off: Hold down the Sleep/Wake button for a few seconds until the red slider appears, then drag the onscreen slider.
- Turn iPad on: Hold down the Sleep/Wake button until the Apple logo appears.
If you don’t touch the screen for a minute or two, iPad locks automatically. You can change how long it takes the screen to lock, or set a passcode to unlock iPad.
Set the auto-lock time: Go to Settings > General > Auto-Lock.
You can use an iPad Smart Cover or iPad Smart Case, sold separately, to automatically lock or unlock an iPad 2 or later.
Use an iPad Smart Cover or iPad Smart Case: Go to Settings > General > iPad Cover Lock/Unlock.
