Apple has finally made good on its promise to bring single sign-on (SSO) for TV providers to the latest Apple TV and iOS devices. 
。

The feature was first announced at WWDC in June and now it's available for select service providers via the latest tvOS 10.1 and iOS 10.2 developer betas. 。

With SSO, users will only need to enter their TV provider username and password once to get access to all content across different video apps included in their subscriptions. 。

Thanks for signing up!。

As my former colleague Christina Warren wrote in June:。

The problem is that logging into [different video apps] is a giant pain in the ass. To get logged in, I almost always have to use a web browser to enter in a code and then login with my provider details. And every few weeks, the login seems to expire and I have to do it all over again.。

• Single sign-on is a step towards making logins and passwords much less of a hassle. The initial rollout of SSO has its limitations, though, since it only works with four TV providers:。

• Dish

• Dish。

• GVTC Communications
