If you forget your passcode, you must restore the iPod touch software. See “Updating and Restoring iPod touch Software” on page 207.

Set how long before your passcode is required: Choose General > Passcode Lock and enter your passcode. Tap Require Passcode, then select how long iPod touch can be locked before you need to enter a passcode to unlock it.

Turn Simple Passcode on or off: Choose General > Passcode Lock, then turn Simple Passcode on or off.

A simple passcode is a four-digit number. To increase security, turn off Simple Passcode and use a longer passcode with a combination of numbers, letters, punctuation, and special characters.

Erase data after ten failed passcode attempts: Choose General > Passcode Lock, enter your passcode, and tap Erase Data to turn it on.

After ten failed passcode attempts, your settings are reset to their defaults and all your information and media are erased:

ÂÂ On iPod touch 3rd generation or later: by removing the encryption key to the data (which is encrypted using 256-bit AES encryption)

ÂÂ On iPod touch 2nd generation: by overwriting the data

Important: You can’t use iPod touch while data is being overwritten. This can take up to four hours or more, depending on the model and storage capacity of your iPod touch. (On iPod touch 3rd generation or later, the encryption key is removed immediately.)
