Comcast wants me to reset my password at EVERY login?

I just made some changes to my plan and now if I logging it works fine but is then followed by a request to reset my password saying my account has been compromised. I reset the password, log in again and get the same message.

So for some reason the account sees my logins as compromised and simply does not work. I can find no way to stop it or specify that this is me logging in.
