Security features
Security features help protect the information on iPod touch from being accessed by others.
Passcodes and data protection
You can set a passcode that you must enter each time you turn on or wake up iPod touch.
Set a passcode: Choose Settings > General > Passcode Lock and enter a 4-digit passcode.
iPod touch then requires you to enter the passcode to unlock it or to display the passcode
lock settings.
Setting a passcode turns on data protection (iPod touch 3rd generation or later). Data protection
uses your passcode as the key for encrypting mail messages and their attachments stored on
iPod touch. (Some apps available from the App Store may also use data protection.) A notice at
the bottom of the Passcode Lock screen in Settings shows whether data protection is enabled.
To increase iPod touch security, turn off Simple Passcode and use a longer passcode with a
combination of numbers, letters, punctuation, and special characters. See “Passcode Lock” on
page 104.
Important:
On an iPod touch 3rd generation that didn’t ship with iOS 4 or later, you must also
restore iOS software to enable data protection. See “Updating iPod touch” on page 137.
