Add Login to Your Laravel Application

Auth0’s Laravel SDK allows you to quickly add authentication, user profile management, and routing access control to your Laravel application. This guide demonstrates how to integrate Auth0 with a new (or existing) Laravel 9 or 10 application.

Test Change

Laravel Installation

If you do not already have a Laravel application set up, open a shell to a suitable directory for a new project and run the following command:

composer create-project --prefer-dist laravel/laravel auth0-laravel-app ^9.0

All the commands in this guide assume you are running them from the root of your Laravel project, directory so you should cd into the new project directory:

cd auth0-laravel-app

SDK Installation

Run the following command within your project directory to install the Auth0 Laravel SDK:

composer require auth0/login:^7.8 --update-with-all-dependencies

Then generate an SDK configuration file for your application:

php artisan vendor:publish --tag auth0

SDK Configuration

Run the following command from your project directory to download the Auth0 CLI:

curl -sSfL https://raw.githubusercontent.com/auth0/auth0-cli/main/install.sh | sh -s -- -b .

Then authenticate the CLI with your Auth0 account, choosing “as a user” when prompted:

./auth0 login

Next, create a new application with Auth0:

./auth0 apps create \
  --name "My Laravel Application" \
  --type "regular" \
  --auth-method "post" \
  --callbacks "http://localhost:8000/callback" \
  --logout-urls "http://localhost:8000" \
  --reveal-secrets \
  --no-input \
  --json > .auth0.app.json

You should also create a new API:

./auth0 apis create \
  --name "My Laravel Application's API" \
  --identifier "https://github.com/auth0/laravel-auth0" \
  --offline-access \
  --no-input \
  --json > .auth0.api.json

This produces two files in your project directory that configure the SDK.

As these files contain credentials it’s important to treat these as sensitive. You should ensure you do not commit these to version control. If you’re using Git, you should add them to your .gitignore file:

echo ".auth0.*.json" >> .gitignore

Login Routes

The SDK automatically registers all the necessary routes for your application’s users to authenticate.

If you require more control over these, or if they conflict with existing routes in your application, you can manually register the SDK’s controllers instead. Please see the SDK’s README for advanced integrations.

Access Control

Laravel’s authentication facilities use “guards” to define how users are authenticated for each request. You can use the Auth0 SDK’s authentication guard to restrict access to your application’s routes.

To require users to authenticate before accessing a route, you can use Laravel’s auth middleware.

Route::get('/private', function () {
  return response('Welcome! You are logged in.');
})->middleware('auth');

You can also require authenticated users to have specific permissions by combining this with Laravel’s can middleware.

Route::get('/scope', function () {
  return response('You have `read:messages` permission, and can therefore access this resource.');

})->middleware('auth')->can('read:messages');

User Information

Information about the authenticated user is available through Laravel’s Auth Facade, or the auth() helper function.

For example, to retrieve the user’s identifier and email address:

Route::get('/', function () {
  if (! auth()->check()) {
  return response('You are not logged in.');

  }
  $user = auth()->user();
  $name = $user->name ?? 'User';
  $email = $user->email ?? '';
  return response("Hello {$name}! Your email address is {$email}.");
});;

User Management

You can update user information using the Auth0 Management API. All Management endpoints are accessible through the SDK’s management() method.

Before making Management API calls you must enable your application to communicate with the Management API. This can be done from the Auth0 Dashboard’s API page, choosing Auth0 Management API, and selecting the ‘Machine to Machine Applications’ tab. Authorize your Laravel application, and then click the down arrow to choose the scopes you wish to grant.

For the following example, in which we will update a user’s metadata and assign a random favorite color, you should grant the read:users and update:users scopes. A list of API endpoints and the required scopes can be found in the Management API documentation.

use Auth0\Laravel\Facade\Auth0;
Route::get('/colors', function () {
$endpoint = Auth0::management()->users();
$colors = ['red', 'blue', 'green', 'black', 'white', 'yellow', 'purple', 'orange', 'pink', 'brown'];
$endpoint->update(
id: auth()->id(),

body: [

    'user_metadata' => [

        'color' => $colors[random_int(0, count($colors) - 1)]

    ]

]

);
$metadata = $endpoint->get(auth()->id());
$metadata = Auth0::json($metadata);
$color = $metadata['user_metadata']['color'] ?? 'unknown';
$name = auth()->user()->name;
return response("Hello {$name}! Your favorite color is {$color}.");
})->middleware('auth');

A quick reference guide of all the SDK’s Management API methods is available here.

Run the Application

You are now ready to start your Laravel application, so it can accept requests:

php artisan serve

Checkpoint

Open your web browser and try accessing the following routes:

• http://localhost:8000 to see the public route.
• http://localhost:8000/private to be prompted to authenticate.
• http://localhost:8000 to see the public route, now authenticated.
• http://localhost:8000/scope to check if you have the read:messagespermission.
• http://localhost:8000/update to update the user’s profile.
• http://localhost:8000/logout to log out.

Next Steps

Excellent work! If you made it this far, you should now have login, logout, and user profile information running in your application.
