MoonShine v4 -- Security (Authentication & Authorization)

1. Authentication Basics

MoonShine ships with a self-contained authentication system backed by its own guard, user model, and middleware stack. The MoonShineAuth helper class provides runtime access:

use MoonShine\Laravel\MoonShineAuth;

$guard = MoonShineAuth::getGuard();          // Active guard instance
$guardName = MoonShineAuth::getGuardName();  // 'moonshine'
$userModel = MoonShineAuth::getModel();      // Configured user model instance

The Authenticate middleware checks moonshineConfig()->isAuthEnabled() and redirects unauthenticated requests to the login page.

2. Configuration

All authentication settings live in config/moonshine.php under the auth key:

// config/moonshine.php
'auth' => [
    'enabled' => true,
    'guard' => 'moonshine',
    'model' => MoonshineUser::class,
    'middleware' => [
        Authenticate::class,
    ],
    'pipelines' => [],
],

'user_fields' => [
    'username' => 'email',
    'password' => 'password',
    'name' => 'name',
    'avatar' => 'avatar',
],

• enabled -- toggle the entire auth system on or off.
• guard -- the Laravel guard name MoonShine uses.
• model -- Eloquent model representing admin users.
• middleware -- array of middleware classes protecting MoonShine routes (v4 uses an array, not a single class).
• pipelines -- ordered list of pipeline classes that run during login.

3. Disabling Authentication

Set enabled to false to remove all auth checks from the panel:

'auth' => [
    'enabled' => false,
],

4. Custom User Model

Replace the default MoonshineUser with your own model:

// config/moonshine.php
'auth' => [
    'model' => App\Models\Admin::class,
],

5. Custom User Fields & Profile

Field mapping via config

When your model uses different column names, map them in user_fields:

// config/moonshine.php
'user_fields' => [
    'username' => 'login',
    'password' => 'pass',
    'name' => 'full_name',
    'avatar' => 'profile_image',
],

Field mapping via MoonShineServiceProvider

$config
    ->userField('username', 'login')
    ->userField('password', 'pass')
    ->userField('name', 'full_name')
    ->userField('avatar', 'profile_image');

Custom profile page

Replace the built-in profile page via config:

// config/moonshine.php
'pages' => [
    'profile' => App\MoonShine\Pages\CustomProfile::class,
],

Or via the service provider:

$config->changePage(
    \MoonShine\Laravel\Pages\ProfilePage::class,
    \App\MoonShine\Pages\CustomProfile::class
);

Custom login page

// config/moonshine.php
'pages' => [
    'login' => App\MoonShine\Pages\CustomLogin::class,
],

6. Role-Based Access

Create middleware to restrict panel access by role, then register it in config/moonshine.php under the middleware array:

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;

class CheckAdminRole
{
    public function handle(Request $request, Closure $next): Response
    {
        if ($request->user() && ! $request->user()->hasRole('admin')) {
            abort(403, 'Access denied.');
        }
        return $next($request);
    }
}

// config/moonshine.php
'middleware' => [
    \App\Http\Middleware\CheckAdminRole::class,
],

7. Authentication Pipelines

Pipelines run after username/password validation but before the session is created. They can redirect users (e.g., to a 2FA challenge page) or add custom checks.

How the pipeline executes

The AuthenticateController sends the request through configured pipelines via Laravel's Pipeline facade. If a pipeline returns a RedirectResponse or MoonShine\Crud\JsonResponse, the login flow stops. Otherwise, authentication proceeds.

Configuring pipelines

Via config:

// config/moonshine.php
'auth' => [
    'pipelines' => [
        TwoFactorAuthentication::class,
        PhoneVerification::class,
    ],
],

Via MoonShineServiceProvider:

$config->authPipelines([
    \App\MoonShine\AuthPipelines\TwoFactorAuthentication::class,
    \App\MoonShine\AuthPipelines\PhoneVerification::class,
]);

Writing a custom pipeline

A pipeline class must implement a handle method that receives the request and a $next closure:

namespace App\MoonShine\AuthPipelines;

use Closure;
use Illuminate\Http\Request;
use MoonShine\Laravel\Models\MoonshineUser;

class PhoneVerification
{
    public function handle(Request $request, Closure $next)
    {
        $user = MoonshineUser::query()
            ->where('email', $request->get('username'))
            ->first();

        if (! is_null($user) && ! is_null($user->getAttribute('phone'))) {
            $request->session()->put([
                'login.id' => $user->getKey(),
                'login.remember' => $request->boolean('remember'),
            ]);

            return redirect()->route('sms-challenge');
        }

        return $next($request);
    }
}

Pipeline order matters -- they execute sequentially.

8. Custom Auth Responses (NEW in v4)

MoonShine v4 introduces authenticateUsing() and logoutUsing() methods to completely override the behavior during authentication and logout.

authenticateUsing

Override behavior after successful authentication. The callback receives a $default closure that executes the standard logic:

// In MoonShineServiceProvider
use Closure;
use Symfony\Component\HttpFoundation\Response;

$config->authenticateUsing(function (Closure $default): Response {
    // Custom redirect after login
    return redirect()->to('/dashboard');

    // Or use the default behavior
    // return $default();
});

logoutUsing

Override behavior during logout:

use Closure;
use Symfony\Component\HttpFoundation\Response;

$config->logoutUsing(function (Closure $default): Response {
    // Custom redirect after logout
    return redirect()->to('/');

    // Or use the default behavior
    // return $default();
});

Combined usage example

use Closure;
use Symfony\Component\HttpFoundation\Response;

$config->authenticateUsing(function (Closure $default): Response {
    logger()->info('User logged in', ['user' => auth()->id()]);

    return $default();
});

$config->logoutUsing(function (Closure $default): Response {
    logger()->info('User logged out');

    return redirect()->to('/');
});

9. Authorization

MoonShine uses standard Laravel Policies. By default, policy checks are disabled on resources. Enable them with the $withPolicy property.

Enabling policies on a resource

namespace App\MoonShine\Resources;

use MoonShine\Laravel\Resources\ModelResource;

class PostResource extends ModelResource
{
    protected bool $withPolicy = true;
}

Available policy methods

Note: In v4, the Ability enum lives at MoonShine\Support\Enums\Ability (was MoonShine\Laravel\Enums\Ability in v3).

Writing a policy

Each policy method receives the auth user model as its first argument. Methods that operate on a specific record also receive the model instance. The first type-hint must match your configured auth model (default: MoonshineUser):

namespace App\Policies;

use App\Models\Post;
use Illuminate\Auth\Access\HandlesAuthorization;
use MoonShine\Laravel\Models\MoonshineUser;

class PostPolicy
{
    use HandlesAuthorization;

    public function viewAny(MoonshineUser $user) { return true; }
    public function view(MoonshineUser $user, Post $model) { return true; }
    public function create(MoonshineUser $user) { return true; }
    public function update(MoonshineUser $user, Post $model) { return true; }
    public function delete(MoonshineUser $user, Post $model) { return true; }
    public function massDelete(MoonshineUser $user) { return true; }
    public function restore(MoonshineUser $user, Post $model) { return true; }
    public function forceDelete(MoonshineUser $user, Post $model) { return true; }
}

Generate a policy scaffold: php artisan moonshine:policy PostPolicy

For models outside app/Models, register policies manually:

use Illuminate\Support\Facades\Gate;

Gate::policy(MoonshineUser::class, MoonshineUserPolicy::class);

See references/auth-extensions.md for a complete policy example with real authorization logic.

10. Additional Authorization Logic

authorizationRules

Add authorization logic that applies across all resources:

use MoonShine\Contracts\Core\ResourceContract;
use MoonShine\Support\Enums\Ability;
use Illuminate\Database\Eloquent\Model;

// In MoonShineServiceProvider boot()
$config->authorizationRules(
    static function (ResourceContract $resource, Model $user, Ability $ability, Model $item): bool {
        return true;
    }
);

Global rules run alongside resource-level policies. When $withPolicy = true, both the policy and all global rules must return true for access to be granted.

11. Socialite

The moonshine/socialite package integrates Laravel Socialite for social login.

composer require moonshine/socialite
php artisan migrate
php artisan vendor:publish --provider="MoonShine\Socialite\Providers\SocialiteServiceProvider"

Configure drivers in config/moonshine-socialite.php, add HasMoonShineSocialite trait to user model, and update auth.model in config. The SocialAuth component is auto-added to profile/login pages. See references/auth-extensions.md for complete setup.

12. Two-Factor Authentication

The moonshine/two-factor package adds TOTP-based 2FA via an auth pipeline.

composer require moonshine/two-factor
php artisan migrate

Add TwoFactorAuthPipe::class to auth.pipelines in config (or via $config->authPipelines()), add TwoFactorAuthenticatable trait to user model, and update auth.model. The TwoFactor component is auto-added to the profile page. See references/auth-extensions.md for complete setup.

13. JWT

MoonShine can operate in API mode with JWT token-based authentication. For full details, see the moonshine-frontend-v4 skill (API section).

v3 to v4 Migration Notes

Login Flow Summary

1. User submits credentials to AuthenticateController::authenticate().
2. LoginFormRequest validates username and password fields, applies rate limiting.
3. If auth pipelines are configured, the request passes through each one in order.
4. If a pipeline returns a redirect or JSON response, the flow stops (e.g., 2FA challenge).
5. If authenticateUsing() is configured, it controls the post-login response.
6. Otherwise, LoginFormRequest::authenticate() calls MoonShineAuth::getGuard()->attempt().
7. On success, the session is regenerated and the user is redirected to the home route.
8. On failure, a ValidationException is thrown with rate-limiter tracking.
