Deleting previous username
I’ve updated my Apple ID and password but I keep getting prompted to sign into my old one
iPhone 8, iOS 12
Question marked as
Did you create a new ID or make a name change to your existing ID? If you are seeing the prompt in Settings, some people have fixed this by signing out of Settings/Your Name/iCloud and then signing back in.
If you are seeing the prompt in the App Store/iTunes and there are updates, a request for another Apple ID password is often caused by updates to apps/purchases that were made when using the other ID. Those purchases are tied to the other ID and can't be transferred. One option is to delete the apps/purchases made by the other ID and download them using the new ID if desired. If necessary, check your purchases history to see which apps/purchases weren’t made by the current ID.
