If you enter your iCloud Security Code incorrectly too many times
Learn what to do if you forgot your iCloud Security Code for iCloud Keychain.
If you recently turned on two-factor authentication, you might need to enter an iCloud Security Code to sign in to iCloud. After you sign in, your device is trusted and you don’t need to enter an iCloud Security Code to use iCloud Keychain.
If you enter the wrong iCloud Security Code too many times when using iCloud Keychain, your iCloud Keychain is disabled on that device, and your keychain in iCloud is deleted. You might see one of these messages:
“Security Code Incorrectly Entered Too Many Times. Approve this iPhone from one of your other devices using iCloud Keychain. If no devices are available, reset iCloud Keychain.”
“Your iCloud Security Code has been entered too many times. Approve this Mac from one of your other devices using iCloud Keychain. If no devices are available, reset iCloud Keychain.”
