Repeating message to log into my Apple ID that I haven't used in over 11 months?
Things have been going along fine. No changes to passwords, nothing. But today, on my iPhone XR running 13.2.3 I get a message to log into my Apple ID. But it was my Apple ID from over a year ago! To try and fix it. I went through and reset my correct Apple ID password and after an hour or so I got the same message on my iPhone. I called Apple but they couldn't help.
Plus, Keychain created a new keychain! I don't know how to recover my Keychain. Why would Apple create a new Keychain because someone changes their password?
Please help. Why would I get a prompt to enter a password for an Apple ID that I haven't used in over 11 months?
As always, thank you smart people.
