Okay, so my Apple ID password expires every 3 months (developer account). On Tuesday, it expired, so I reset it, entered my new password on all my devices, all good to go. This afternoon, out of the blue, my iPhone prompted me to enter my Apple ID/iCloud password in Settings. I did that, the password didn't work. I tried going to appleid.apple.com, entering the password, no go. I then reset my password, looked into my account, nothing changed. I never received an email about the password changing (other than when I legit reset my password after it failed). I called Apple Support, they said everything looked okay and could possibly be a server issue of some kind. While on the phone with Apple Support, they asked me to re-enter my Apple ID account to change my security questions. I tried entering, no go. My password stopped working again! The agent could do nothing, but just said to reset the password and this time, reset my security questions. I did, and got an email saying my password was changed (but before that, nothing!). I was feeling very freaked and weirded out, because this was the first time this ever happened. I even had copied the password in TextEdit and pasted it into the box, but no go (that way, I knew I definitely typed it right). Once I resetted my password, I changed my questions then signed out. I feel very concerned, especially as I never got an email saying my password changed when it failed. The agent was a bit unhelpful, saying there wasn't much he could do. (This was with a senior tech.) I'm at work, so it could possibly be something weird with our work wifi/Internet, but I don't know. What could be going on? I'm very concerned. Thanks. If you need any clarification, let me know.
