Creating Custom Authentication and Authorization in Laravel 8 - A Step-by-Step Guide

Published on : March 26,2023

In Laravel 8, authentication and authorization are managed using the built-in authentication system called Laravel Jetstream. However, it is possible to create a custom authentication and authorization system to suit your specific needs.

Here are the steps to create custom authentication and authorization in Laravel 8:

Step 1: Create a new middleware

The first step is to create a new middleware that will handle the authentication and authorization logic. You can create a middleware using the make:middleware Artisan command:

php artisan make:middleware CustomAuth

This command will create a new file called CustomAuth.php in the app/Http/Middleware directory.

Step 2: Implement the middleware logic

Next, you need to implement the authentication and authorization logic in the middleware. In this example, we'll use a simple authentication logic based on a user's email and password.

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;

class CustomAuth
{
    public function handle($request, Closure $next)
    {
        $credentials = $request->only('email', 'password');

        if (Auth::attempt($credentials)) {
            return $next($request);
        }

        return response('Unauthorized.', 401);
    }
}

This middleware will check the user's email and password against the database using the Auth::attempt method. If the authentication is successful, the middleware will allow the request to pass through to the next middleware in the stack. Otherwise, it will return a 401 Unauthorized response.

Step 3: Register the middleware

Once you've implemented the middleware, you need to register it in the app/Http/Kernel.php file. Add the following line to the $routeMiddleware array:

'custom.auth' => \App\Http\Middleware\CustomAuth::class,

Step 4: Apply the middleware to routes

Finally, you can apply the middleware to routes or groups of routes using the middleware method:

Route::get('/dashboard', function () {
    // Only authenticated users can access this route
})->middleware('custom.auth');

You can also apply the middleware to a controller by adding the following line to the constructor:

$this->middleware('custom.auth');

That's it! You've now created a custom authentication and authorization system in Laravel 8. Of course, this is just a simple example, and you'll likely want to modify the middleware logic to suit your specific needs.
