How to set a Passcode (iOS 4.1 or later)
- From the Home Screen, open Setting
- Select Open General
- Scroll down and tap on Passcode Lock The default passcode is four digits -- if you would like to set an alphanumeric passcode, slide the Simple Passcode toggle to Off
- Select Turn Passcode On
- Enter a four-digit passcode, or an alphanumeric passcode of any length
- Re-type your passcode to confirm
- Set Require Passcode to the desired time -- this will be the amount of idle time before your iPad 2 will require you to enter the passcode
- Turn Erase Data On to enable automatic erase in the case of 10 passcode failures
- Tap Enable to confirm
- Optional: Picture Frame allows a locked device to display photos similar to a screen saver. These photos may include personally identifiable information. Turn this Off to prevent someone from seeing photos on the device. Alternatively, select what photos are displayed in the Photo Frame settings listed on the left-hand side of the screen.
Demonstration
- Lock your device with the Sleep Button, wait the amount of time set to require the passcode, and wake up with the Sleep or Home Buttons. Slide to Unlock the device as normal.
- The Passcode entry message appears. If the Simple Passcode option was disabled, the prompt will be different.
- An Incorrect passcode was entered! Make sure not to do this ten times in a row (unlikely if you know the code).
Once a passcode is set, several other options and settings for the iOS will require this to be entered before changing such as audio volume limits and accepting encryption keys.
You can even wipe the iPad, erasing all data if the Passcode is entered wrong ten times straight.
