YouTube API v3 get all channels associated with a logged in user

Question

Is it possible to get all the channels associated with a logged in user account, using youtube\'s version 3 API (https://developers.google.com/apis-explorer/#p/youtube/v3/).

Answer 1

OAuth2 allows login in with only one channel, so that's not possible.

OAuth2 already gives user a choice to pick the channel they want to authorize and give access, so you don't have to implement it anyways.
