Single Sign-on for Network TV Everywhere apps on iOS devices and Apple TV
The next time you sign in to use various Network TV Everywhere apps on your iOS device, you may be asked, "Allow this network to use your TV Provider subscription?"
Once you choose "Allow", you won't have to sign in to most TV Everywhere apps individually.
This feature is available with iOS 10 or greater running on your iPad or iPhone 6 or greater. It's also available on the latest version of Apple TV.
