Logging into any service on Apple TV is a pain. The text-entry field is one long line, and if you’ve got a particularly lengthy username or password for apps on the Apple TV, entering them can take much longer than it should.
Twitter-owned Digits is offering its own take on a solution with an SDK that tvOS developers can implement in their apps and let users type in a short string of numbers and letters that they get from their iPhone, rather than the full-on username and password combination.
This could solve the problem altogether, and it’s not much more tricky than using an app for Two-Step Authentication, which we all do now, anyway (or should).
