Comcast Email on iphone

I had to recently change my xfinity password and my phone wouldn't accept the new password.  I think bcuz MFA was turned on.  I turned MFA off and again attempted to log in and it still won't accept my password.  Keeps saying creds are incorrect.  What do I need to do to get my email back on my phone?  I have already read your online documentation.  Please advise.........
