Get authenticated user with Laravel Passport and grant password

php laravel-5 oauth-2.0 laravel-passport

You forgot the appropriate middleware.

Route::get('/user', function(Request $request) {    return Auth::user();})->middleware('auth:api');

The authentication flow is not fired when you don't mention the auth middleware. That's why you get null.

I had the same problem with you. And i solved it after I manually defined the auth guard.

Route::get('/user', function (Request $request) {  return auth()->guard('api')->user();});

You need to pass the Access token back with every request. Please check the documentation for this part here
