Hey Macrumors community! My iPhone started bugging me with this very annoying pop-up/notification which reads "Sign-in required. Enter the password for [my email address]." I don't know what this is, as neither the notification nor the pop-up give any indication as to what service/account I'm supposed to be signing in to. If I recall correctly, the last time something like this happened it specifically asked me to sign in to iCloud. Needless to say, I have been cancelling the request and haven't entered my password. My efforts trying to google the issue weren't too successful, as most of the posts refer to the iCloud thing mentioned above. Any idea what this might be? Thanks!
