I was trying to login to icloud.com when it refused to log me in and gave me this message (look at the attached photo). I've had this Apple ID and used it for icloud.com and iCloud on my iPhone since I bought the phone so the issue is not that it's a new ID and not activated or whatever. Plus it's working normally on my iPhone. I don't know why this happened or whether it's just a temporary thing. Please help as I don't want to delete my Apple ID on the phone and re-enable it because I'm afraid to lose my data.
