re: Stopping auto login for cable provider

Spectrum used to do that. It's called home based authentication. After months of complaining to them, I now get a popup saying "logging in with this account" with my local account which is internet only. I click "no, log in to another account" and I can then use my credentials from my other account to login. I have tv and internet at one location and internet only at another so I can use the login from the tv account to stream at the internet only location.
It took them about a year or so to finally get it that way so if it was possible for spectrum to do it, I'm sure cox can as well.
