That's a great question, @Lefk! I love binge-watching on Netflix. Thanks for posting to the Xfinity Forum. To watch Netflix on your account, you'll need a compatible box and to use your primary Xfinity ID to log in. Please let me know if you have any issues after reviewing the links?
How do I watch Netflix (which is part of my Xfinity package) on my laptop? Is it possible? I cant find a place to log into Netflix on Xfinity app.
using your X1 go to the netflix internet app then to settings. you will find an entry to show or generate a userid/password to use on non-X1 to sign into netflix.
