Social login for Filament through Laravel Socialite

Add OAuth2 login through Laravel Socialite to Filament. OAuth1 (eg. Twitter) is not supported at this time.

Installation

Install the package via composer:

composer require dutchcodingcompany/filament-socialite

Publish and migrate the migration file:

php artisan vendor:publish --tag="filament-socialite-migrations"
php artisan migrate

Other configuration files include:

php artisan vendor:publish --tag="filament-socialite-config"
php artisan vendor:publish --tag="filament-socialite-views"
php artisan vendor:publish --tag="filament-socialite-translations"

You need to register the plugin in the Filament panel provider (the default filename is app/Providers/Filament/AdminPanelProvider.php). The following options are available:

use DutchCodingCompany\FilamentSocialite\FilamentSocialitePlugin;
use DutchCodingCompany\FilamentSocialite\Provider;
use Filament\Support\Colors;
use Laravel\Socialite\Contracts\User as SocialiteUserContract;
use Illuminate\Contracts\Auth\Authenticatable;

// ...
->plugin(
    FilamentSocialitePlugin::make()
        // (required) Add providers corresponding with providers in `config/services.php`. 
        ->providers([
            // Create a provider 'gitlab' corresponding to the Socialite driver with the same name.
            Provider::make('gitlab')
                ->label('GitLab')
                ->icon('fab-gitlab')
                ->color(Color::hex('#2f2a6b'))
                ->outlined(false)
                ->stateless(false)
                ->scopes(['...'])
                ->with(['...']),
        ])
        // (optional) Override the panel slug to be used in the oauth routes. Defaults to the panel ID.
        ->slug('admin')
        // (optional) Enable/disable registration of new (socialite-) users.
        ->registration(true)
        // (optional) Enable/disable registration of new (socialite-) users using a callback.
        // In this example, a login flow can only continue if there exists a user (Authenticatable) already.
        ->registration(fn (string $provider, SocialiteUserContract $oauthUser, ?Authenticatable $user) => (bool) $user)
        // (optional) Change the associated model class.
        ->userModelClass(\App\Models\User::class)
        // (optional) Change the associated socialite class (see below).
        ->socialiteUserModelClass(\App\Models\SocialiteUser::class)
);

This package automatically adds 2 routes per panel to make the OAuth flow possible: a redirector and a callback. When setting up your external OAuth app configuration, enter the following callback URL (in this case for the Filament panel with ID admin and the github provider):

https://example.com/admin/oauth/callback/github

A multi-panel callback route is available as well that does not contain the panel ID in the url. Instead, it determines the panel ID from an encrypted state input (...?state=abcd1234). This allows you to create a single OAuth application for multiple Filament panels that use the same callback URL. Note that this only works for stateful OAuth apps:

https://example.com/oauth/callback/github

If in doubt, run php artisan route:list to see which routes are available to you.

CSRF protection

(Laravel 11.x users can ignore this section)

If your third-party provider calls the OAuth callback using a POST request, you need to add the callback route to the exception list in your VerifyCsrfToken middleware. This can be done by adding the url to the $except array:

protected $except = [
    '*/oauth/callback/*',
    'oauth/callback/*',
];

For Laravel 11.x users, this exception is automatically added by our service provider.

See Socialite Providers for additional Socialite providers.

Icons

You can specify a custom icon for each of your login providers. You can add Font Awesome brand icons made available through Blade Font Awesome by running:

composer require owenvoke/blade-fontawesome

Registration flow

This package supports account creation for users. However, to support this flow it is important that the password attribute on your User model is nullable. For example, by adding the following to your users table migration. Or you could opt for customizing the user creation, see below.

$table->string('password')->nullable();

Domain Allow list

This package supports the option to limit the users that can login with the OAuth login to users of a certain domain. This can be used to setup SSO for internal use.

->plugin(
    FilamentSocialitePlugin::make()
        // ...
        ->registration(true)
        ->domainAllowList(['localhost'])
);

Changing how an Authenticatable user is created or retrieved

You can use the createUserUsing and resolveUserUsing methods to change how a user is created or retrieved.

use DutchCodingCompany\FilamentSocialite\FilamentSocialitePlugin;
use Laravel\Socialite\Contracts\User as SocialiteUserContract;

->plugin(
    FilamentSocialitePlugin::make()
        // ...
        ->createUserUsing(function (string $provider, SocialiteUserContract $oauthUser, FilamentSocialitePlugin $plugin) {
            // Logic to create a new user.
        })
        ->resolveUserUsing(function (string $provider, SocialiteUserContract $oauthUser, FilamentSocialitePlugin $plugin) {
            // Logic to retrieve an existing user.
        })
        ...
);

Change how a Socialite user is created or retrieved

In your plugin options in your Filament panel, add the following method:

// app/Providers/Filament/AdminPanelProvider.php
->plugins([
    FilamentSocialitePlugin::make()
        // ...
        ->socialiteUserModelClass(\App\Models\SocialiteUser::class)

This class should at the minimum implement the FilamentSocialiteUser interface, like so:

namespace App\Models;

use DutchCodingCompany\FilamentSocialite\Models\Contracts\FilamentSocialiteUser as FilamentSocialiteUserContract;
use Illuminate\Contracts\Auth\Authenticatable;
use Laravel\Socialite\Contracts\User as SocialiteUserContract;

class SocialiteUser implements FilamentSocialiteUserContract
{
    public function getUser(): Authenticatable
    {
        //
    }

    public static function findForProvider(string $provider, SocialiteUserContract $oauthUser): ?self
    {
        //
    }
    
    public static function createForProvider(
        string $provider,
        SocialiteUserContract $oauthUser,
        Authenticatable $user
    ): self {
        //
    }
}

Check if the user is authorized to use the application

You can use the authorizeUserUsing method to check if the user is authorized to use the application. Note: by default this method check if the user's email domain is in the domain allow list.

use DutchCodingCompany\FilamentSocialite\FilamentSocialitePlugin;
use Laravel\Socialite\Contracts\User as SocialiteUserContract;

->plugin(
    FilamentSocialitePlugin::make()
        // ...
        ->authorizeUserUsing(function (FilamentSocialitePlugin $plugin, SocialiteUserContract $oauthUser) {
            // Logic to authorize the user.
            return FilamentSocialitePlugin::checkDomainAllowList($plugin, $oauthUser);
        })
        // ...
);

Change login redirect

When your panel has multi-tenancy enabled, after logging in, the user will be redirected to their default tenant. If you want to change this behavior, you can call the 'redirectAfterLoginUsing' method on the FilamentSocialitePlugin.

use DutchCodingCompany\FilamentSocialite\FilamentSocialitePlugin;
use DutchCodingCompany\FilamentSocialite\Models\Contracts\FilamentSocialiteUser as FilamentSocialiteUserContract;
use DutchCodingCompany\FilamentSocialite\Models\SocialiteUser;

FilamentSocialitePlugin::make()
    ->redirectAfterLoginUsing(function (string $provider, FilamentSocialiteUserContract $socialiteUser, FilamentSocialitePlugin $plugin) {
        // Change the redirect behaviour here.
    });

Filament Fortify

This component can also be added while using the Fortify plugin plugin.

## in Service Provider file
public function boot()
{
    //...
    
    Filament::registerRenderHook(
        'filament-fortify.login.end',
        fn (): string => Blade::render('<x-filament-socialite::buttons />'),
    );
}

Filament Breezy

This component can also be added while using the Breezy plugin plugin.

You can publish the login page for Filament Breezy by running:

php artisan vendor:publish --tag="filament-breezy-views"

Which produces a login page at resources/views/vendor/filament-breezy/login.blade.php.

You can then add the following snippet in your form:

<x-filament-socialite::buttons />

Events

There are a few events dispatched during the authentication process:

InvalidState(InvalidStateException $exception): When trying to retrieve the oauth (socialite) user, an invalid state was encountered
Login(FilamentSocialiteUserContract $socialiteUser): When a user successfully logs in
Registered(FilamentSocialiteUserContract $socialiteUser): When a user and socialite user is successfully registered and logged in (when enabled in config)
RegistrationNotEnabled(string $provider, SocialiteUserContract $oauthUser): When a user tries to login with an unknown account and registration is not enabled
SocialiteUserConnected(FilamentSocialiteUserContract $socialiteUser): When a socialite user is created for an existing user
UserNotAllowed(SocialiteUserContract $oauthUser): When a user tries to login with an email which domain is not on the allowlist

Scopes

Scopes can be added to the provider on the panel, for example:

use DutchCodingCompany\FilamentSocialite\FilamentSocialitePlugin;
use DutchCodingCompany\FilamentSocialite\Provider;

FilamentSocialitePlugin::make()
    ->providers([
        Provider::make('github')
            ->label('Github')
            ->icon('fab-github')
            ->scopes([
                // Add scopes here.
                'read:user',
                'public_repo',
            ]),
    ]),

Optional parameters

You can add optional parameters to the request by adding a with key to the provider on the panel, for example:

use DutchCodingCompany\FilamentSocialite\FilamentSocialitePlugin;
use DutchCodingCompany\FilamentSocialite\Provider;

FilamentSocialitePlugin::make()
    ->providers([
        Provider::make('github')
            ->label('Github')
            ->icon('fab-github')
            ->with([
                // Add scopes here.
                // Add optional parameters here.
                'hd' => 'example.com',
            ]),
    ]),

Stateless Authentication

You can add stateless parameters to the provider configuration in the config/services.php config file, for example:

'apple' => [
    'client_id' => '...',
    'client_secret' => '...',
    'stateless'=>true,
]

Note: you cannot use the state parameter, as it is used to determine from which Filament panel the user came from.
