Can't sign into email on Samsung phone

My mother's email  stopped syncing and wants her to re-enter her password. However, this screen is all I get when I try and enter the password .  There's nothing actionable on this page.  I tried removing the account and re-adding it but same thing. I cleared the cache of the email app and restarted  the phone.  I've also turned off 2 step verification so it stops trying to open the Xfinity app.  It seems like it's trying to open the Xfinity app for verification, but never actually does.  Just stuck in this loop.
