Hello. I read the on-device-authentication documentation and it seems to me that it is used in conjunction with Roku Pay. Not sure if this would be the best way to implement what I need. I need to do as the Youtube channel does, where it says "Log in with smartphone". Then you open the Youtube app on your smartphone and there is a warning "Log in to Youtube on Roku..." and after I click "connect", returning to the Youtube channel on Roku, it appears: "you are logged in as. .." Did Youtube implement this using on-device-authentication?
