Auth guard for Laravel that completely relies on Google Login and doesn't persist

Overview

Sometimes your small application doesn't need local persisted user repository at all. At times like that, it's nice to rely on external account repository, eg. Google – nowadays practically everybody got a Google account?

This authentication guard relies on Google token. Every time your app needs to authenticate a user, it will redirect user to Google, then back. If the token is valid, your user will be considered authenticated within your app.

No persistence at all, just some session caching.

And you can of course specify allowed Google users or domains if your application is private.

Dependencies

• Laravel Socialite
• Laravel 5.3.*

Installation

First install the package using Packagist:

$ composer require dusterio/laravel-google-guard

Add the package service provider to your config/app.php to providers array:

Dusterio\LaravelGoogleGuard\Integrations\LaravelServiceProvider::class,

You should see two extra routes after this:

$ php artisan route:list
| GET|HEAD | auth/google            |                   | Dusterio\LaravelGoogleGuard\Http\LoginController@redirectToProvider     | guest,web    |
| GET|HEAD | auth/google/callback   |                   | Dusterio\LaravelGoogleGuard\Http\LoginController@handleProviderCallback | guest,web    |

Configure the guard in config/auth.php:

    'guards' => [
        /// Your existing guards
        /// ...    
        'google' => [
            /*
             * For consistency, return a dummy (not persisted) class holder.
            */
            'userClass' => '\App\User',

            /*
             * Remember users for this number of seconds.
             */
            'timeout' => 3600,

            /*
             * Users that can use the app. If left empty, everybody is allowed.
             */
            'whitelist' => [
                'admin@.',
            ]
        ]              
    ]

Make it a default guard in the same file config/auth.php:

        'web' => [
            'driver' => 'google',
            'provider' => 'users',
        ],

Add your google key and secret to config/services.php, eg.:

    'google' => [
        'client_id' => env('GOOGLE_CLIENT_ID'),
        'client_secret' => env('GOOGLE_CLIENT_SECRET'),
        'redirect' => env('APP_URL') . '/auth/google/callback',
    ],

That's it – you are ready to go!
