Login and Logout

[galazzaroni]

Hello, many laravel tutorials to do apis using oauth 2.0 explain how to login, logout in the generated AuthController.
I installed this library and I see that you have to call oauth / token passing as parameter grant_type, client_id, client_secret, username and password. This would replace the Laravel AuthController login? I will consume the api from Ionic, that is, for each user I must repeat these parameters (grant_type, client_id, client_secret)?
I am right?
Thank you.
