In routes :
Route::group(['middleware' => 'web'], function () {
Route::auth();
Route::get('/home', 'HomeController@index');
});
Remove Route::auth() and set all routes manualy to add routes names.
To help you here is auth() function in router :
public function auth()
{
// Authentication Routes...
$this->get('login', 'Auth\AuthController@showLoginForm');
$this->post('login', 'Auth\AuthController@login');
$this->get('logout', 'Auth\AuthController@logout');
// Registration Routes...
$this->get('register', 'Auth\AuthController@showRegistrationForm');
$this->post('register', 'Auth\AuthController@register');
// Password Reset Routes...
$this->get('password/reset/{token?}', 'Auth\PasswordController@showResetForm');
$this->post('password/email', 'Auth\PasswordController@sendResetLinkEmail');
$this->post('password/reset', 'Auth\PasswordController@reset');
}
