What information does iCloud Keychain store?
iCloud Keychain stores credit card numbers and expiration dates—without storing or autofilling the security code—and passwords and usernames, Wi-Fi passwords, Internet accounts, and more.

How does iCloud Keychain protect my information?
iCloud protects your information with end-to-end encryption, which provides the highest level of data security. Your data is protected with a key that's made from information unique to your device, and combined with your device passcode, which only you know. No one else can access or read this data, either in transit or storage. Learn more.
What happens when I turn off iCloud Keychain on a device?
When you turn off iCloud Keychain for a device, you're asked to keep or delete the passwords and credit card information that you saved. If you choose to keep the information, it isn't deleted or updated when you make changes on other devices. If you don't choose to keep the information on at least one device, your Keychain data will be deleted from your device and the iCloud servers.
Can Apple recover my iCloud Security Code?
No. If you enter your iCloud Security Code incorrectly too many times, you can't use that iCloud Keychain. You can contact Apple Support to verify your identity and try again. After several incorrect attempts, your keychain is removed from Apple's servers, and you need to set it up again.
