Security Features

Security features help protect the information on iPhone 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 iPhone.

Set a passcode: Choose Settings > General > Passcode Lock and enter a 4-digit passcode, then enter the passcode again to verify it. iPhone then requires you to enter the passcode to unlock it or to display the passcode lock settings.

Setting a passcode turns on data protection. Data protection uses your passcode as the key for encrypting mail messages and their attachments stored on iPhone. (Data protection may also be used by some apps available in the App Store.) A notice at the bottom of the Passcode Lock screen in Settings shows whether data protection is enabled.

To increase iPhone 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 195.

Important: On an iPhone 3GS that didn’t ship with iOS 4 or later, you must also restore iOS software to enable data protection. See “Restoring iPhone” on page 257.

Prevent voice dialing when iPhone is locked: In Settings, choose General > Passcode Lock and turn Voice Dial off. Unlock iPhone to use voice dialing.
