Hello sir, I'm follow your blog but I got lost in `not_authorized` and `auth.guest`.

In the `not_authorized`, should I put the `not_authorized` in `config->auth.php` or in `resource->lang->en->auth.php`.

In the `auth.guest`, should I put it in `$middleware` or `$routeMiddleware`?

Hi [japet saberon](https://hashnode.com/@japet), I am happy that my post is helping you. Let me explain a bit better.

The `not_authorized` in this case is a localization key, and it should be entered in the `resource\lang\en\auth.php`, you can read more about localization directly from the laravel website: laravel.com/docs/localization - but let me know if you still struggle.

About the `auth.guest` middleware, as mentioned on my post, you should put it in $middleware property of your `app/Http/Kernel.php` class.

Let me know if you need more help :)
