+## How add a custom field to Laravel 5.4 default login controller.
+
+In this php example (`app/Http/Controllers/Auth/LoginController.php`) my model is called `Client` 
+and the custom field for login validation is `status`. (`Client->status`)
+
+Add in your `resources/lang/en/auth.php` file :
+
+```php
+    'failed_status' => 'Your account is inactive yet. Please confirm your e-mail address.',
+```
+
+Feel free to customize!
