User Profile

Hi there,I'm building a tvOS channel and I wonder what are the Apple recommendations for linking the device with a particular user account. To give you an idea what I mean, when developing Roku channels, they recommend something they call Rendezvous linking (https://developer.roku.com/en-ca/docs/developer-program/authentication/authentication-and-linking.md), which is basically a handoff of a shared secret between the backend and the device. The device displays a code on the screen and user types it in throught an authenticated web interface in his browser. Once that is successfully done, the backend will send the device a secure token, which the device then uses in all subsequent requests in order to authenticate itself.Does Apple recommend doing something similar in order to link the device to a specific user account? If yes, is there any documentation available on this topic? If no, what is the recommendation?Thanks!
