Netflix Login

You could try using your Comcast email and password. If that doesn't work, cancel Netflix through Comcast and subscribe directly with Netflix through their web site. Do not sign up through an app or Apple/Google gets a cut, just as Comcast gets a cut of your Netflix subscription fee. By directly signing up, you are free to use it easily on any device. The only 'drawback' is that you have to log in the first time on each device (although with Roku, doing it on one may auto-login on other Roku devices on that account.)

Hey there! Glad you reached out, you can find your login details on the x1 Netflix app. To do so, go into settings and account, you will find a menu item where you can get a username/password to access on other devices from that menu. Hope that helps! Please let me know if you have any question or trouble.
