Aiming to help you enjoy instant access to video apps that your pay TV subscription includes, Apple has launched a new single authentication tool to log in to your cable or satellite-TV provider on your iPhone, iPad, iPod touch, or Apple TV.
The new feature is available in the US only and can be used on CenturyLink Prism, DirecTV, Dish, GVTC, GTA, Hawaiian Telcom, Hotwire, MetroCast, Sling.
Even if your provider supports single sign-on, there still might be apps that you need to open and sign in to individually.
You can sign in with only one TV provider at a time from your Apple TV running tvOS 10 or later versions or from your iPhone, iPad, iPod Touch having iOS 10 or later versions.
To keep your apps updated, turn on automatic updates: On Apple TV, go to Settings > Apps. For iOS, go to Settings > iTunes & App Store > Updates.
