Unlocking an iCloud account
I got an email saying my sons iCloud “has been temporarily disabled for security reason. When you see this alerts, you can go to Visit Apple to unlock your account.Your Account will permanently disabled if you do not verify your account under 24 hours. It is some how a secondary email to my Apple ID and I can’t delete it.
Any solutions ???
