How to stop email address showing in iPhone 5S settings?

Previously before the update to iOS 8, you could simply log out of your Apple id in settings & not have your email still showing. But now your email is still displayed there & can't remove it even after logging out. I even tried resetting Network settings & the other settings, only way to remove it is to factory erase the phone completely.

Is there atleast a way to log into your account online & create a Username you can use to login instead of your email that will show instead? Or is there a way to remove it?

Try resting your keyboard autoFills that should work
