iCloud Keychain
iCloud Keychain keeps your website user names and passwords, and credit card information
that you set up with Safari, up to date on iPad and your other iOS devices and Macs running
OS X Mavericks.
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 iPad enter your user name and password info, making login easy. See Fill in
forms on page 49.
Note: Some websites do not support AutoFill.
iCloud Keychain works on all your approved iOS 7 devices and Macs running OS X Mavericks.
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 and
follow the onscreen instructions. If you’ve 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: Your iCloud Security Code cannot be retrieved by Apple. If you forget your security
code, you’ll 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 ll in names, passwords, or credit card info on sites that support it, tap a text
eld, then tap AutoFill.
To protect your personal information, set a passcode if you turn on iCloud Keychain and AutoFill.
