Support oauth2 workflow #54
Description
It seems like this system is really well set-up to have a good UX for CLI workflows that interoperate with web services following the oauth2 authentication workflow. Users could use a browser and redirect to the web server to get the access token without moving between desktop applications, and the application could probably simplify things by just getting an access token or authorization code from the redirect which could be handled by the html forms web server. Would need to consult the spec if this would be specific to auth server implementations/vendors or if this could be a standards-based solution.
Good test case: list emails in inbox with Google APIs & gmail
