Xfinity login information change

How do you switch login info for same provider? I need to use a different login email for xfinity.

I tried everything in the ipad, removing the tv provider, resetting the network settings, etc. The answer to this dilemma is that the individual apps such as NBC, ABC, FOX, etc store your previous login information. You must remove and reinstall the apps. You will then receive a prompt to re-enter login information and you can change it then.
