Quick Start with Affinidi Login

The Affinidi Login can be integrated with any application that supports OIDC flow.

Before you begin

1. Set up Affinidi Vault account. Follow the guide below if you haven’t set it up yet.

Set up Affinidi Vault

1. Set up an Affinidi Vault account using the web app or install the mobile app .

The same installation steps for mobile app.

2. Click on Start if you are creating a new account, or click on Restore from Backup if you have an existing backup of your Affinidi Vault.

Use this guide to learn how to migrate your existing Affinidi Vault account.

3. Secure your Vault by providing a passphrase. Use this passphrase to unlock your Vault.

3. Provide your Email Address to verify with OTP.

After successfully providing the OTP, you are redirected to your Affinidi Vault dashboard.

Vault Passphrase

Remember to keep your passphrase in a secure location since it cannot be retrieved if forgotten, even with your backup. If you forget it, you must setup a new Vault.

2. 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.

3. Optionally, install the Affinidi CLI. Follow the guide below if it hasn’t been installed.

Set up Affinidi CLI

1. Download and install NodeJS on your machine if you haven’t set it up yet.

Node Version

Affinidi CLI requires Node version 18 and above.

2. Install Affinidi CLI using Node Package Manager (npm).

npm install -g @affinidi/cli

3. Verify that the installation is successful.

affinidi --version

Create Login Configuration

To integrate Affinidi Login into your application, you must create the Login Configuration to configure on your OIDC settings.

4. To create a Login Configuration, you can either use Affinidi CLI or  Affinidi Portal.

Expand the section for your preferred method:

affinidi start

affinidi login create-config \
--name='<Name>' \
--redirect-uris='<Redirect URIs>'

{
  "ari": "ari:identity:ap-southeast-1:687b8872-a618-dt63-8978-e72ac32daeb1:login_configuration/c4f74d936cd31bde1c1fd3c1050bb76s",
  "projectId": "687b8872-a618-4e52-8978-e72ac32daec2",
  "configurationId": "c4f74d936cd31bde1c1fd3c1050bb62d",
  "name": "...",
  "auth": {
    "clientId": "<AUTH.CLIENT_ID>",
    "clientSecret": "<AUTH.CLIENT_SECRET>",
    "issuer": "https://<PROJECT_ID>.apse1.login.affinidi.io"
  },
  "redirectUris": [
    "..."
  ],

  },
  "creationDate": "2023-08-11T06:26:37Z",
  "tokenEndpointAuthMethod": "client_secret_post"
}

Using Affinidi Portal

1. Go to  Affinidi Login under the Services section.

2. 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.

3. Click on create and confirm if all the details are correct.

4. 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.

5. After copying the Client ID and Client Secret and closing the popup, you are redirected back to the Affinidi Login page.

Login Configuration uses a default Presentation Definition (presentationDefinition) and ID Token Mapping (idTokenMapping) to request the user’s email address during the authentication flow.

You can modify these defaults using  Affinidi Portal and Affinidi CLI to have additional authentication requirements and request other data from the user. See this documentation.

Setting Up Your Application

If you are using libraries or plugins to enable OpenID Connect flow on your application, please refer to their documentation on configuring these settings. You can explore our labs to learn how to integrate Affinidi Login with well-known frameworks and other IDP solutions.

5. Go to your application’s OIDC settings and configure the following details to integrate Affinidi Login into your application’s login flow.

{
  "clientId": "<AUTH.CLIENT_ID>",
  "clientSecret": "<AUTH.CLIENT_SECRET>",
  "scope": "openid offline_access",
  "authorizationUrl": "<AUTH.ISSUER>/oauth2/auth",
  "tokenUrl": "<AUTH.ISSUER>/oauth2/token"
}

Once you have successfully set up the details on your application, you can enable a passwordless login for your end-users to provide a seamless experience using Affinidi Vault as the Identity Provider.

6. After the user successfully verifies their identity through Affinidi Login and consents to share their info (e.g Email VC), it redirects the user back to your application with the ID Token.

Affinidi Login automatically adds users who successfully authenticate to your application to the default user group. You can create additional User Groups to organise your users and provide them with the necessary authorisation to access your application resources and apply different business logic after the user successfully authenticates.
