Download And Installation

  • Log into your WordPress instance as an admin.
  • Go to the WordPress Dashboard -> Plugins and click on Add New.
  • Search for a WordPress OAuth Single Sign On plugin and click on Install Now.
  • Once installed click on Activate.

Step 1: Setup Laravel Passport as OAuth Provider

  • Create a laravel project on your local machine using command and set it up:
  • composer create-project --prefer-dist laravel/laravel blog

  • Install laravel passport
  • composer require laravel/passport

  • Go to config/app.php and add below provider
  • Laravel\Passport\PassportServiceProvider::class,

  • Run php artisan migrate command
  • Run php artisan passport:install command
  • Go to app/User.php model class, add HasApiTokens trait to the code:
  • namespace App;
    use Laravel\Passport\HasApiTokens;
    use Illuminate\Contracts\Auth\MustVerifyEmail;
    use Illuminate\Foundation\Auth\User as Authenticatable;
    use Illuminate\Notifications\Notifiable;
    class User extends Authenticatable
    use HasApiTokens, Notifiable;
    * The attributes that are mass assignable.
    * @var array

    protected $fillable = [ 'name', 'email', 'password', ];
    * The attributes that should be hidden for arrays.
    * @var array

    protected $hidden = [ 'password', 'remember_token', ];
    * The attributes that should be cast to native types.
    * @var array

    protected $casts = [ 'email_verified_at' => 'datetime', ]; }
  • Go to app/Providers/AuthServiceProvider.php, add Passport routes to the service code is given below:
  • namespace App\Providers;
    use Laravel\Passport\Passport;
    use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
    use Illuminate\Support\Facades\Gate;
    class AuthServiceProvider extends ServiceProvider
    * The policy mappings for the application.
    * @var array

    protected $policies = [ // 'App\Model' => 'App\Policies\ModelPolicy', ];
    * Register any authentication / authorization services.
    * @return void

    public function boot()
  • Go to config/auth.php change the api driver token to passport as we are going to use Passport library.
  • 'guards' => [
    'web' => [
    'driver' => 'session',
    'provider' => 'users',
    'api' => [
    'driver' => 'passport',
    'provider' => 'users',
    'hash' => false,
  • Now Set up a demo resource you can make an API route in routes/api.php file.
  • To get Client ID and Client Secret run following commands: php artisan passport:client It will ask you the following questions:
  • Which user ID should the client be assigned to?:
    > 1
    What should we name the client?:
    > Demo OAuth2 Client Account
    Where should we redirect the request after authorization?
    > http://localhost/oauth2_client/callback.php
    New client created successfully.
    Client ID: 1
    Client secret: zMm0tQ9Cp7LbjK3QTgPy1pssoT1X0u7sg0YWUW01

  • To create a UserInfo endpoint manually, in the app/Http/Controllers, create a file UserController.php:
  • use App\Http\Controllers\Controller;
    use Illuminate\Http\Request;
    use App\User;
    class UserController extends Controller
    public function get(Request $request)
    $user_id = $request->get("uid", 0);
    $user = User::find($user_id);
    return $user;
  • Also, register the API route by adding the below line in routes/api.php file:
  • Route::middleware('auth:api')->get('/user/get', 'UserController@get');
  • Now you can connect OAuth client with Laravel Passport (OAuth Provider) and the following endpoints are:
  • Authorization endpoint: http://your-laravel-site-url/oauth/authorize
    Token endpoint: http://your-laravel-site-url/oauth/token
    User info endpoint: http://your-laravel-site-url/api/user/get

Step 2: Setup WordPress as OAuth Client

  • Go to Configure OAuth tab and configure App Name, Client ID, Client Secret from provided Endpoints.
  • openid is already filled but if it doesn't work then configure scope as User.Read and for fetching group info use scope is
  • Click on Save Settings to save the configuration.
  • OAuth/OpenID Ping Identity Single Sign On SSO WordPress create-newclient configure-endpoints

Step 3: User Attribute Mapping.

  • User Attribute Mapping is mandatory for enabling users to successfully login into WordPress. We will be setting up user profile attributes for WordPress using below settings.
  • Finding user attributes

    • Go to Configure OAuth tab. Scroll down and click on Test Configuration.
    • test congifuration
    • You will see all the values returned by your OAuth Provider to WordPress in a table. If you don't see value for First Name, Last Name, Email or Username, make the required settings in your OAuth Provider to return this information.
    • OAuth/OpenID Ping Identity Single Sign On SSO WordPress create-newclient configuration-test-result
    • Once you see all the values in Test Configuration, go to Attribute / Role Mapping tab, you will get the list of attributes in a Username dropdown.
    • OAuth/OpenID Ping Identity Single Sign On SSO WordPress create-newclient attribute/role mapping

Step 4: Login Settings / Sign In Settings.

  • The settings in SSO Settings tab define the user experience for Single Sign On. To add a login widget on your WordPress page, you need to follow below steps.
  • Sign In Settings

    • Go to WordPress Left Panel > Appearances > Widgets.
    • Select miniOrange OAuth. Drag and drop to your favourite location and save.
