Laravel Passport

Tip: If you only want to write a SPA application but don't need an API for some other use (for example, a mobile application), you can avoid much of the complexity by using Inertia.js.

Very important: Don't use the command passport:install to avoid issues.

Passport use cases

• Using Passport only in central application
• Using Passport only in tenant application
• Using Passport in both the central and tenant application

Passport keys

• Manage Passport keys
  • Shared keys
  • Tenant-specific keys

Using Passport only in central application

You don't have to do anything special in this use case, just install Laravel Passport as its official documentation explains:
Laravel Passport official documentation

Using Passport only in tenant application

To use Laravel Passport inside the tenant application, you must follow the following steps:

1. Add this code to the register method in your AppServiceProvider to prevent Passport migrations from running in the central application:

   Passport::ignoreMigrations();
   

2. Register Passport routes adding this code to the boot method in your AuthServiceProvider:

   Passport::routes(null, ['middleware' => [
       InitializeTenancyByDomain::class, // Or whatever tenant identification middlewares you're going to use
       PreventAccessFromCentralDomains::class,
   ]]);
   
   

3. Publish Passport migrations running php artisan vendor:publish --tag=passport-migrations command and move (not copy) all of them to database/migrations/tenant/ directory.

4. Publish Passport config file running php artisan vendor:publish --tag=passport-config command. After that, open config/passport.php file and set storage database connection to null. This will make Passport use the default connection:

   return [
       'storage' => [
           'database' => [
               'connection' => null,
           ],
       ],
   ];
   

5. Create Passport Clients in your tenant database seeder like this:

   public function run()
   {
       $client = new ClientRepository();
   
       $client->createPasswordGrantClient(null, 'Default password grant client', 'http://your.redirect.path');
       $client->createPersonalAccessClient(null, 'Default personal access client', 'http://your.redirect.path');
   }
   

   You can set your tenants database seeder class in config/tenancy.php file at seeder_parameters key.

6. Create Passport keys following Manage Passport keys section.

Using Passport in both the central and tenant application

To use Laravel Passport on central and tenant application, you must follow the following steps:

1. Enable [Universal Routes]({{ $page->link('universal-routes') }}) feature.

2. Register Passport routes adding this code to the boot method in your AuthServiceProvider:

   Passport::routes(null, ['middleware' => [
       'universal',
       PreventAccessFromCentralDomains::class,
   ]]);
   
   

3. Publish Passport migrations running php artisan vendor:publish --tag=passport-migrations command and make a copy of all of them to database/migrations/tenant/ directory.

4. Publish Passport config file running php artisan vendor:publish --tag=passport-config command. After that, open config/passport.php file and set storage database connection to null. This will make Passport use the default connection:

   return [
       'storage' => [
           'database' => [
               'connection' => null,
           ],
       ],
   ];
   

5. Create Passport Clients in your central and tenant database seeders like this:

   public function run()
   {
       $client = new ClientRepository();
   
       $client->createPasswordGrantClient(null, 'Default password grant client', 'http://your.redirect.path');
       $client->createPersonalAccessClient(null, 'Default personal access client', 'http://your.redirect.path');
   }
   

   You can set your tenants database seeder class in config/tenancy.php file at seeder_parameters key.

6. Create Passport keys following Manage Passport keys section.

Manage Passport keys

Shared keys

If you want to use the same Passport keys for all your tenants and your central application (in case you are using Passport in your central app), you only have to run php artisan passport:keys command and you are done.

Tenant-specific keys

Note: The security benefit of doing this isn't probably that big, since you're likely already using the same APP_KEY for all tenants. This is a relatively complex approach, so before implementing it, make sure you really want it.

If you want to use an unique Passport keys for each tenant, there are multiple ways you can store and load tenant Passport keys, but the most straightforward way is to store the keys in the Tenant model and load them into the passport configuration using the [Tenant Config]({{ $page->link('features/tenant-config') }}) feature.

Once the [Tenant Config]({{ $page->link('features/tenant-config') }}) feature is enabled, simply map your tenant Passport keys into the boot method of your TenancyServiceProvider as follows:

\Stancl\Tenancy\Features\TenantConfig::$storageToConfigMap = [
    'passport_public_key' => 'passport.public_key',
    'passport_private_key' => 'passport.private_key',
],
