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 iPhone enter your user name and password info, making login easy. See Fill in
forms on page 67.
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 use of iCloud Keychain from one of those devices, or use your iCloud Security Code.
Important: If you forget your iCloud Security Code, you have to start over and set up your iCloud
Keychain again.
Set up AutoFill. Go to Settings > Safari > Passwords & AutoFill. Make sure Names and Passwords,
and Credit Cards, are turned on (they’re on by default). To add credit card info, tap Saved
Credit Cards.
The security code for your credit card is not saved—you have to enter that manually.
To automatically fill in names, passwords, or credit card info on sites that support it, tap a text
field, then tap AutoFill.
To protect your personal information, set a passcode if you turn on iCloud Keychain and AutoFill.
Limit Ad Tracking
Restrict or reset Ad Tracking. Go to Settings > Privacy > Advertising. Turn on Limit Ad Tracking to
prevent apps from accessing your iPhone advertising identifier. For more information, tap About
Advertising & Privacy.
