I'm specifically referring to iOS with the window fade. Of course the issue with it is that the user would have to notice the lack-of the effect on the fake popups (or apps trying to fake the users app icons/wallpaper) My point is that literally anything would be better than a generic UIAlertController with a password field that exists today, I can fake one in literally ten seconds and have it be remotely triggered by a key on a server to pass through app review. Anything added would enhance security for users.
