Apple ID sign-in

I keep getting a message popping up on my iPhone screen, “Enter your Apple ID in Settings”. It comes up really often. I ignore it, but it keeps popping up. I thought perhaps some 3rd party was trying to get me to log in, so I didn’t. I don’t wish to log into Apple. When I do, I’ll enter my ID and password. How do I stop it, short of actually logging in?
