Question about on device authentication
I see apps like Netflix and Youtube both make users login/signup using rendezvous method(showing a code to end user that needs to be entered in a website/app) but on the documentation here it says
"SVOD and TVOD channels (and other subscription services) must implement on-device authentication to pass certification." & "For SVOD and TVOD channels (and other subscription services), on-device authentication deprecates the "rendezvous" registration method."
In my opinion rendezvous make a lot more sense rather than making user enter email, password. Some users don't even have passwords if they used google/facebook to sign up in the first place. Can I implement rendezvous method for a channel that will implement subscription in the future? Or I must use on device authentication?
