Update: On March 3, 2020 Airbnb sunset the Airbnb Apple TV app.

Apple TV Authentication Example

This is an example authentication server for an Apple TV or other device that doesn't lend itself to password entry. Check out https://medium.com/airbnb-engineering/apple-tv-authentication-a156937ea211#.yyj7id33m for details about the workflow implemented here.

Much of the basic Sinatra/Warden implementation is based on Steve Klise's excellent example: https://github.com/sklise/sinatra-warden-example. The most interesting things to look at are auth_token.rb and the :nonce Warden strategy in app.rb.
