Allow access to Control Center when iPad is locked. Go to Settings > Control Center. See 
 on page 28.
Erase data after ten failed passcode attempts. Go to Settings > General > Passcode Lock and 
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 iPad software. See 
 on page 129.
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 
 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 fill in names, passwords, or credit card info on sites that support it, tap a text 
field, then tap 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 iPad advertising identifier. For more information, tap
