Switch between users using Api Authentication (Passport) on laravel

I have an Angular 4 app, using Laravel as API, and i want to add a function , where i can switch between users for admin users.

i cant use this because i need a token:

public function autologin(Request $request, $id) {
   $credentials = Auth::loginUsingId($id);
   return $credentials;
}

I didn't find any post about this, or in the documentation I using oauth2 for authentication (http://ift.tt/2g9Rb5K) how can i achieve that ?
