Implicit Grant

This way is recommended and the only auth-process which does not need a server-side exchange of keys. With this approach, you directly get a Token object after the user authed your application. You won't be able to refresh the token. If you want to use the internal Http server, please add "http://localhost:YOURPORT" to your application redirect URIs.
