Security
Security features help protect the information on your iPod touch from being accessed by others.
Use a passcode with data protection
For better security, you can set a passcode that must be entered each time you turn on or wake
up iPod touch.
Set a passcode. Go to Settings > Passcode, then set a 4-digit passcode.
Setting a passcode turns on data protection, using your passcode as a key to encrypt Mail
messages and attachments stored on iPod touch, using 256-bit AES encryption. (Other apps may
also use data protection.)
Increase security. Turn o Simple Passcode and use a longer passcode. To enter a passcode that’s
a combination of numbers and letters, you use the keyboard. If you prefer to unlock iPod touch
using the numeric keypad, set up a longer passcode using numbers only.
Allow access to features when iPodtouch is locked. Go to Settings > Passcode. Optional
features include:
•
Today (see Notication Center on page 31)
•
Notications View (see Notication Center on page 31)
•
Siri (if enabled; see Siri settings on page 43)
•
Passbook (see Chapter 26, Passbook, on page 117 )
•
Reply with Message (see Make and answer calls on page 69)
Allow access to Control Center when iPodtouch is locked. Go to Settings > Control Center. See
Control Center on page 30.
Erase data after ten failed passcode attempts. Go to Settings > Passcode, then tap Erase Data.
After ten failed passcode attempts, all settings are reset, and all your information and media are
erased by removing the encryption key to the data.
If you forget your passcode, you must restore the iPod touch software. See Restore iPod touch on
page 162.
iCloud Keychain
iCloud Keychain keeps your Safari website user names and passwords, credit card information,
and Wi-Fi network information up to date. iCloud Keychain works on all your approved devices
(iOS 7 or later) and Mac computers (OS X Mavericks or later).
iCloud Keychain works with Safari Password Generator and AutoFill. When you’re setting up a
new account, Safari Password Generator suggests unique, hard-to-guess passwords. You can use
AutoFill to have iPod touch enter your user name and password info, making login easy. See Fill
in forms on page 58.
Note:Some websites do not support AutoFill.
iCloud Keychain is secured with 256-bit AES encryption during storage and transmission, and
cannot be read by Apple.
Set up iCloud Keychain. Go to Settings > iCloud > Keychain. Turn on iCloud Keychain, then
follow the onscreen instructions. If you set up iCloud Keychain on other devices, you need to
approve the use of iCloud Keychain from one of those devices, or use your iCloud Security Code.
