Xfinity Constantly asking me to change my password

Over the last few weeks, Xfinity has been sending me an email and asking me to reset my password. I can't log into Xfinity streaming services unless I change it. I thought that I would try two factor authentication and tell them to not check for two factor after the first long in. But there is no way to enter a two factor code into Channels DVR. If I don't use two factor, I get asked to change my password every few days.

Does anyone else have this issue?

Very well known issue with Xfinity.
Use the search and you will find a few threads on it issue.
There are possible fixes depending on things.

What are you using for your server?

Update your sever to pre-release
Update the Chrome to latest version also has fixed it for many.

I am using a PC running Windows 10 for my server.
I updated to pre-release and updated Chrome to the latest version.
Changed my Xfinity password (again).
We'll see what happens in a couple of days if Xfinity wants me to change the password again...

I’ve had this issue with Fios. After making a sub account and using that, it stopped.

XI made another Xfinity account, but now I can't see how to change the Xfinity username inside Channels. I can see where I can update the Xfinity password in Channel settings, but not the username.

You can either remove and readd the source, or use command line curl to update it.
