Once the "remember_me" parameter is set to true, we will get 3 2 extra parameters in the json response (i.e remember_me_token & remember_me_expires_in) The remember_me_expires_in value will be set to 30 days. The client have to save the client_id & remember_me_token in their localStorage, cookie etc. So, for next authentication, they have to use this token as seen in the request json tab. By this way, if this set it is not necessary for the user to enter their credentials every time (i.e the credentials are not required to generate the auth token. Rather the remember_me_token will generate the auth token each time)
