First, we have to create a fresh Laravel 8 application. If you already installed Laravel 8 application then skip this step.

composer create-project --prefer-dist laravel/laravel blog 8.0

The above command blog is our project name and 8.0 means we install Laravel 8.0 version.

Install Laravel UI package

Install the Laravel UI official package for creating auth scaffolding in the Laravel 8 application.

composer require laravel/ui:^3.0

Generate auth scaffold

After installation Laravel UI package. Now, We are able to scaffold our auth with Bootstrap, Vue, React, etc. And if we need to scaffold with Vue then run the command bellow command:

php artisan ui vue --auth

Output

Vue scaffolding installed successfully.
Please run "npm install && npm run dev" to compile your fresh scaffolding.
Authentication scaffolding generated successfully.

Install NPM

Now, we have to install all our NPM dependencies. And compile the assets the command npm run dev

npm install && npm run dev

Example

Now ready Laravel 8 auth application. Now check whether authentication is installed or not.

Check login

http://127.0.0.1:8000/login

Check registration

http://127.0.0.1:8000/register

Disable register route

In most cases, we clients want to disable the new user registration system. Then you go to the /routes/web.php route file and add the below code.

Auth::routes(['register' => false]);

Route restriction

Laravel 8 was successfully installed with auth system. Now protect our routes for unauthenticated users by using a two-way routes file and a second controller file.

#routes/web.php

Route::get('/dashboard', 'App\Http\Controllers\DashboardController@index')->middleware('auth');

And we can protect by our controller in the constructor function __construct

<?php
#App\Http\Controllers\DashboardController.php

class UserController extends Controller
{
    public function __construct()
    {
        $this->middleware('auth');
    }

    public function index(){
        // code here
    }
}

Now how to check the user is authenticated or not authenticated in the view or anywhere in the controller. so we can use auth()->check()

if(auth()->check()) {
    // code here
}

And get current user data.

Change the necessary configuration

Laravel auth default auth successfully log in it will redirect/home path. but in most cases we can redirect /dashboard or another page so we can put public const HOME=’/dashboard’ form the RouteServiceProvider.php file.

#App\Providers\RouteServiceProvider.php

public const HOME = '/dashboard';

public function username()
{
    return 'username';
    // code here
}
