Iphone keeps asking for password you must enter both your apple account and password
My iPhone keeps asking for my account password at least 3 times a day! It prompts me to say “ apple account required: please sign in to your apple account in settings”. Then I click on settings and enter my password (which I know is correct as I physically typed it into my online apple account to log into this forum!) - but the when I hit enter it brings up another popup stating “you must enter BOTH your Apple account and password”. However there is no place for me to enter my account - the prompt only gives space for a password. This had been going on for about 2 months. I just updated to the latest ios software this morning and its still doing it!
iPhone 14, iOS 18
