Protecting Your ‘Pad
Starting up your iPad is easy. Just press the Home button and your iPad is ready to go in an instant. This quick access to the Home screen and your apps is one of the best features of the iPad. It can also be a liability because anyone can do it, on your iPad, any time. To prevent unauthorized access, you can set a four-digit Passcode. You can also set a longer, more complex passcode if you wish.
Settings > General > Passcode Lock > Turn Passcode On
Enter a four-digit passcode. Then to be sure you meant it, enter the same four digits again. Note – you MUST remember your passcode. Otherwise you can be locked out of your own device. If this happens, you’ll need to restore your iPad on the computer you sync it with.
Your passcode is now active and the Passcode Lock screen will be displayed when you wake your iPad. Your Sleep setting (Auto-Lock) and Passcode interval do not need to be the same. For example, you may set your iPad to go to sleep after five minutes of inactivity, but have your Passcode take effect after a longer interval, up to four hours. That way, you won’t need to enter your passcode every time your iPad goes to sleep. To change Passcode settings: Settings > General > Passcode Lock. Tap Require Passcode. Choose how long you want the iPad to be idle before the Passcode Lock takes effect.
