Authentication to dropbox on tvOS

Thanks for all of the information and screenshots guys, that's very helpful. I'll bring this up with the team internally.

One thing that may work with the existing infrastructure though would be how Apple TV apps of the current generation work for connecting external accounts. That is, the Apple TV app gives the user a short URL for the app's web site to browse to on an Internet connected device with a browser, and that web site processes a standard OAuth 2 app authorization flow. Upon redirected back to the app's web site, it can send down the necessary token to the TV app. That would offer a better user experience, especially if the user is already signed in to Dropbox on their phone, for example, as they'd only have to type in the short URL on their device, as opposed to typing in their full Dropbox credentials on the Apple TV (possibly including a second factor, etc.).
