# Affinidi Login with PHP > In this guide, learn how to enable passwordless login in your application using Laravel Framework and Socialite. The Affinidi Login can be integrated with any application that supports OIDC flow. In this lab, we will use the [Laravel](https://laravel.com/) framework with [Socialite](https://laravel.com/docs/10.x/socialite) from the available sample applications to take you through the step-by-step guide for creating a Login Configuration and setting up the application to implement passwordless authentication for end-users. ## Before you begin - Set up Affinidi Vault account. Follow the guide below if you haven’t set it up yet. Set up Affinidi Vault Set up an Affinidi Vault account using the [Web Vault](https://vault.affinidi.com) or install the Mobile Vault (for [Android](https://play.google.com/store/apps/details?id=com.affinidi.vault&pcampaignid=web_share)). The same setup steps for Mobile Vault. - Click on Get started if you are creating a new account, or click on Restore from Backup if you have an existing backup of your Affinidi Vault. Provide the passphrase to secure your Affinidi Vault. You have the option to enable Biometrics to unlock your Affinidi Vault easily instead of using passphrase. GIF - Enter your email address to register with the Affinidi Vault. An OTP will be sent to this email for verification. GIF - Enter the OTP sent to the email you have provided for verification to complete the setup. GIF After successfully providing the OTP, you are redirected to the Affinidi Vault dashboard. Important Note Remember to keep your passphrase in a secure location. Use the Passphrase Reset feature in Affinidi Vault settings to generate the PDF files and keep them safe, which you can use to recover access to your Affinidi Vault if you forget your passphrase. - Get the Redirect URI of your application for OIDC. This is the URI configured on your Login Configuration to receive the idToken after successful authorisation. - Optionally, install the Affinidi CLI. Follow the guide below if it hasn’t been installed. Set up Affinidi CLI - Download and install [NodeJS](https://nodejs.org/en/download) on your machine if you haven’t set it up yet. Node Version Affinidi CLI requires Node version 18 and above. - Install Affinidi CLI using Node Package Manager (npm). ```bash npm install -g @affinidi/cli ``` - Verify that the installation is successful. ```bash affinidi --version ``` - Setup [Composer](https://getcomposer.org/download/) on your machine to install PHP dependencies in Laravel. ## Download Application You can [clone](https://github.com/affinidi/reference-app-affinidi-vault/tree/main/samples/affinidi-laravel-socialite) this sample application from our Github and start exploring how to integrate Affinidi Login to provide a passwordless login experience for your end-users. Important Note The downloadable sample application is provided only as a guide to quickly explore and learn how to integrate the components of Affinidi Trust Network into your application. This is NOT a Production-ready implementation. Do not deploy this to a production environment. ## Create Login Configuration To create a Login Configuration, you can either use Affinidi CLI or [Affinidi Portal ](/dev-tools/affinidi-portal.md#create-a-login-configuration). Expand the section below for your preferred method: Laravel Sample App Settings: Name: Laravel Socialite Redirect URIs: http://localhost:8010/login/affinidi/callback Using Affinidi CLI - Log in to Affinidi CLI by running: ```Bash affinidi start ``` - Once you have successfully logged in, create the Login Configuration by running: ```Bash affinidi login create-config \ --name='Laravel Socialite' \ --redirect-uris='http://localhost:8010/login/affinidi/callback' ``` - --name is what you want your login configuration to be called. - --redirect-uris is the URL on your application where the user gets redirected after the successful authentication. Learn more on how to manage your Login Configurations using [Affinidi CLI](/dev-tools/affinidi-cli.md#affinidi-vpa-configs). Using Affinidi Portal - Go to [Affinidi Login ](https://portal.affinidi.com/affinidiLogin) under the Services section. - Click on the Create Login Configuration and provide the required details. - Name is the string that describes your login configuration. - Redirect URIs is the URL on your application where the user gets redirected after the successful authentication. - Click on create and confirm if all the details are correct. - After confirming the details, another popup shows the Client ID and Client Secret for your Login Configuration. Copy the generated Client Credentials and use them to integrate with Affinidi Login. - After copying the Client ID and Client Secret and closing the popup, you are redirected back to the Affinidi Login page. Login Configuration uses the default Presentation Definition (presentationDefinition) and ID Token Mapping (idTokenMapping) that is used to request the user’s email address during the authentication flow. Important Safeguard the Client ID and Client Secret diligently; you'll need them for setting up your IdP or OIDC-compliant applications. Remember, the Client Secret will be provided only once. ## Set up the Sample Application After creating the Login Configuration required to set up the sample application. Let’s start setting up the Laravel application by configuring the following settings: #### Configure Env Variables Create the .env file using the following command: ```Bash cp .env.example .env ``` Set the environment variables based on the auth credentials received from the Login Configuration created earlier: ```JSON { "auth": { "clientId": "", "clientSecret": "", "issuer": "https:// .apse1.login.affinidi.io" } } ``` Set the following fields in the .env file ```yaml PROVIDER_CLIENT_ID="" PROVIDER_CLIENT_SECRET="" PROVIDER_ISSUER="" ``` #### Install Dependencies Go to the Laravel directory and install the Laravel dependencies with Composer using the following command: Setup [Composer](https://getcomposer.org/download/) on your machine to install PHP dependencies in Laravel. ```Bash composer install ``` #### Running the Application After configuring the .env file and installing the required Laravel dependencies, run the application using the following command: ```Bash php artisan serve ``` After successfully running the command, go to [http://localhost:8010](http://localhost:8010) to access the page with the Affinidi Login button. ## Key Changes to Sample Application #### Controllers Laravel Controller class allow developers to define and group related routes to handle incoming requests. In our sample application, we have defined the App\Http\LoginRegisterController class to handle the request: ```php namespace App\Http\Controllers; use App\Http\Controllers\Controller; use Illuminate\Http\Request; use Illuminate\Support\Facades\Auth; use Laravel\Socialite\Facades\Socialite; class LoginRegisterController extends Controller { public function login() { return view('login'); } public function home() { if (session("user")) { return view('dashboard'); } return redirect()->route('login') ->withErrors([ 'email' => 'Please login to access the home.', ]); } public function logout(Request $request) { Auth::logout(); $request->session()->invalidate(); $request->session()->regenerateToken(); return redirect()->route('login') ->withSuccess('You have logged out successfully!'); ; } public function affinidiLogin(Request $request) { return Socialite::driver('affinidi')->redirect(); } public function affinidiCallback(Request $request) { try { $user = Socialite::driver('affinidi')->user(); session(['user' => $user]); return redirect()->intended('home'); } catch (\Exception $e) { return redirect()->route('login') ->withError($e->getMessage()); } } } ``` In the LoginRegisterController class, we have defined 2 key endpoints to integrate Affinidi Login. - affinidiLogin that triggers a redirect using the Socialite OAuth provider to initiate the Affinidi Login authentication flow. - affinidiCallback to receive the callback response from Affinidi Login after successful user authentication. We call the Socialite OAuth provider to parse the ID Token that contains the user’s information. We received information based on the defined [Presentation Definition and ID Token Mapping](/products/affinidi-elements/affinidi-login/presentation-definition-id-token-mapping.md) in Login Configuration. #### AffinidiSocialite Provider Using the composer.json, we have imported [@affinidi/laravel-socialite-affinidi](https://packagist.org/packages/affinidi/laravel-socialite-affinidi) to register Affinidi as the Auth Provider using Socialite in Laravel. After importing the required library, we have defined Affinidi in the App\Providers\AppServiceProvider to bootstrap the AffinidiSocialite driver to handle the Affinidi Login flow. ```php namespace App\Providers; use Illuminate\Support\ServiceProvider; use Laravel\Socialite\Contracts\Factory; class AppServiceProvider extends ServiceProvider { /** * Register any application services. */ public function register(): void { // } /** * Bootstrap any application services. */ public function boot(): void { $socialite = $this->app->make(Factory::class); //Setup affinidi driver \Affinidi\SocialiteProvider\AffinidiSocialite::extend($socialite); } } ``` ## Summary ```mermaid sequenceDiagram actor User participant Laravel participant Affinidi Login participant Affinidi Vault participant Affinidi Verifier User->>Laravel: My Login Laravel->>Affinidi Login: Authenticate user Note over Laravel, Affinidi Login: login_challenge Affinidi Login->>Affinidi Vault: Verify user identity Note over Affinidi Login, Affinidi Vault: presentationDefinition Affinidi Vault->>User: Request user confirmation to share Email VC User->>Affinidi Vault: User confirmed consent to share Email VC Affinidi Vault->>Affinidi Vault: Generate VP Token from VC Affinidi Vault->>Affinidi Login: Send Email VP Token Affinidi Login->>Affinidi Verifier: Validate VP Token Note over Affinidi Login, Affinidi Verifier: vp_token, presentation_submission, presentation_definition Affinidi Login->>Affinidi Login: Generate idToken Affinidi Login->>Laravel: Send generated idToken from VP Laravel->>User: Provide access to the user ``` Using the Laravel framework as the sample application, we have configured it to integrate with Affinidi Login as the Auth provider and parse the idToken sent by the Affinidi Login to confirm the user’s successful authentication using the Affinidi Vault.
