You see, I'm trying to make a user authentication system with Laravel.
For this, I'm supposed to write this code in CMD: php artisan make:auth and that will make me see the following: 
But even though I get a confirmation message ( Authentication scaffolding generated successfully ), the image does not appear. Where do I go to see her?
You put
php artisan serve
and it tells you how to see your screen.
The php artisan make:auth command creates you model, driver and path for user authentication and registration.
And the php artisan serve command launches the server.
For Laravel (Laravel is an open source framework to develop web applications and services with PHP), the server should always be working properly, it is obvious but sometimes we forget how easy it is.
