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: Go to 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 from 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 o Simple Passcode and use a longer passcode with a
combination of numbers, letters, punctuation, and special characters. See “Passcode Lock” on
page 165.
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 “Updating and restoring iPhone software” on page 175.
Prevent voice dialing when iPhone is locked: Go to Settings > General > Passcode Lock and turn
Voice Dial o. Unlock iPhone to use voice dialing.
Find My iPhone
Find My iPhone helps you locate and secure your iPhone using the free Find My iPhone app
on another iPhone, iPad, or iPod touch, or using a Mac or PC web browser signed in to
www.icloud.com or www.me.com.

 Send a Message or Play a Sound: Lets you compose a message that will appear on your

set to silent.
 Remote Passcode Lock: Lets you remotely lock your iPhone and create a 4-digit passcode, if
you haven’t set one previously.
 Remote Wipe: Lets you protect your privacy by erasing all media and data on iPhone, restoring
it to factory settings.
Important: Before you can use its features, Find My iPhone must be turned on in either iCloud or
MobileMe settings on your iPhone. Find My iPhone can be turned on only in one account.
