Some users are reporting they are unable to sign out at this point after selecting no. If you declined this prompt, you will not be able to play. When signing in with an account that has never played Halo: The Master Chief Collection before, you will be presented with a "Let this app access your info" prompt.

MCC -> Properties -> Updates -> Disable Steam Cloud sync for this game It's on by default and might mess with some of the changes you try to make.
