Security features help protect the information on your iPad from being accessed by others.
Initially, iPad doesn't require you to enter a passcode to unlock it. You can set a passcode that must be entered each time you turn on or wake up iPad.
Set a passcode. Go to Settings > General > Passcode Lock and 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 iPad, using 256-bit AES encryption. (Other apps may also use data protection.)
Increase security. Turn off 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 iPad using the numeric keypad, set up a longer passcode using numbers only.
Allow access to features when iPad is locked. Go to Settings > General > Passcode Lock. Optional features include:
Allow access to Control Center when iPad is locked. Go to Settings > Control Center. See Control Center.
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.
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. 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.
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.
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 Learn More.
