Set up single sign-on with your TV provider on Apple TV
Single sign-on simplifies access to entertainment apps like HBO Max and FXNOW. With it, you sign in only once on your Apple TV to get immediate access to all the supported apps that require your cable or satellite pay TV credentials.
Note: Some cable and internet providers support zero sign-on, which simplifies the sign-on process even further by automatically signing you in. Follow on-screen prompts during initial set-up.
You can activate single sign-on during Apple TV set-up or in Settings. Once you’ve signed in, any other supported app you have access to will automatically authenticate you, eliminating the need to sign in again.
Tip: If you’ve saved passwords on your iOS device with iOS 12 or later, or on your iPadOS device with iPadOS 13 or later, you can autofill account passwords on Apple TV. See Set up accounts for other apps and channels on Apple TV.
Activate or deactivate single sign-on
Open Settings on Apple TV.
Go to Users and Accounts > TV Provider and select your TV provider.
Sign in with your username and password for that provider.
To deactivate single sign-on after you’ve signed in, select Sign Out.
Note: If you have more than one Apple TV, you must sign in once for each Apple TV to use this feature. Single sign-on is also available in iOS and iPadOS.
