Hi, i have in common/config my modules configuration

        'user' => [

            'class' => 'dektrium\user\Module',

            'modelMap' => [

                'User' => 'common\models\User',

            ],

            'enableRegistration'=>false,

            'enableGeneratingPassword'=> false,

            'enableUnconfirmedLogin' => false,

            'enableConfirmation'=>true,

            'confirmWithin' => 21600,

            'cost' => 12,

            'admins' => ['admin']...

My controller

    {

                $module=\Yii::$app->getModule('user')->enableGeneratingPassword;

                print_r ($module=true);
