The major shortcoming of Apple TV app is the absence of a Remote app for the iPhone. Specifically, when you initially set it up the Netflix password has to be adjusted manually. Similarly, Hulu password also needs to be setup using Apple TV remote. But Facebook has recently introduced a new SDK for tvOS that has turned out to be a good way to avoid the cumbersome onboarding experience.
Like on iOS, Facebook allows you to integrate its SDK in your apps to make the developers leverage the ‘Login with Facebook’ feature. But there is a turning point in the same. Instead of enquiring about the Facebook password, you will be prompted to avoid the step initially.
As you move further, you will notice that the login screen tells you to move to facebook.com/device on the phone. You ought to enter 8 character confirmation code if you have logged in from your phone, thereby associating the Facebook account with Apple TV. If you aren’t on your phone, log in to Facebook first and then move further.
Luckily, Facebook is not the only one using this technique, even YouTube is utilizing it since long. If YouTube app is downloaded on Apple TV, you can easily access it by connecting it to your Google account. Likewise, Android TV uses the same method to login mechanism for devices running Android TV.
