Trying to enter your username and password on Apple TV is a bit of a cumbersome affair. Twitter hopes to make it easier for you to login to your Apple TV with its Digits service being rolled out now to tvOS developers. The screen shows an authentication code which users enter at digits.com/appletv on a different device. This will complete the authentication process and personalized settings should take effect afterwards. And according to Twitter, it just needs a “few lines of code” for Digits to work.
