 ## Create Auth0 connections
 
+You can leverage either an [Enterprise Connection](#enterprise-connection), or a [Custom Social Connection](#custom-social-connection) to connect Criipto Verify with Auth0.
+
+### Enterprise Connection
+
 To integrate Criipto Verify with Auth0, you create an Auth0 OpenID Connect connection to communicate with Criipto Verify. Because Auth0 will not pass the `acr_values` to Criipto Verify, you will have to create a new connection for every eID option that you intend to use. (`acr_values` is a parameter in the `/authorize` request to Criipto Verify needed to specify which kind of eID is requested)
 
 For those cases, you can leverage our login-method specific metadata endpoints. Each of these contain an embedded and base64-encoded variant of the "raw" value normally supplied in the `acr_values`.

+### Custom Social Connection
+
+Alternatively, you can leverge a <a href="https://auth0.com/docs/authenticate/identity-providers/social-identity-providers/oauth2" target="_blank">Custom Social Connection</a> to integrate with Criipto Verify via OpenID Connect.
+
+#### Create the OIDC connection
+
+1. Go to Auth0 dashboard for your tenant and under **Authentication** choose **Social**.
+2. Select **Create Connection**, go to the bottom of the list, then choose **Create Custom**.
+3. Enter **Connection name**.
+4. Under **Authorization URL** enter the [authorize URL](https://docs.criipto.com/verify/guides/authorize-url-builder/) to which your users will be redirected to log in to your application, e.g. `https://yourdomain.criipto.id/oauth2/authorize?scope=openid&client_id=urn:criipto:samples:no1&redirect_uri=https://jwt.io&response_type=code`
+5. Under **Token URL**, enter your token endpoint: `https://yourdomain.criipto.id/oauth2/token`
+6. Under **Client ID** enter the **Client ID/Realm** from your Criipto Verify application.
+7. Under **Client Secret** enter the **Client Secret** generated by Criipto Verify when you enabled the [OAuth2 Code Flow](##configure–the-oauth2-code-flow).
+8. Add the required <a href="https://auth0.com/docs/authenticate/identity-providers/social-identity-providers/oauth2#fetch-user-profile-script" target="_blank">Fetch User Profile Script</a> using your `userInfo` endpoint, e.g.:
+
+```javascript
+function fetchUserProfile(accessToken, context, callback) {
+  request.get(
+    {
+      url: 'https://yourdomain.criipto.id/oauth2/userinfo',
+      headers: {
+        Authorization: 'Bearer ' + accessToken,
+      },
+    },
+    (err, resp, body) => {
+      if (err) {
+        return callback(err);
+      }
+      if (resp.statusCode !== 200) {
+        return callback(new Error(body));
+      }
+      let bodyParsed;
+      try {
+        bodyParsed = JSON.parse(body);
+      } catch (jsonError) {
+        return callback(new Error(body));
+      }
+      const profile = {
+        user_id: bodyParsed.uuid,
+        name: bodyParsed.name,
+      };
+      callback(null, profile);
+    }
+  );
+}
+```
+
+9. Create a connection by clicking **Create**.
+10. Make sure to enable the created connection for your Auth0 application.
+11. Lastly, add Auth0's callback URL (`https://{yourAuth0Domain}/login/callback`) to your Criipto Verify application. Go to your Criipto Dashboard, and enter the Auth0 Callback URL under **Callback URLs** in Criipto Verify application management.
+
+#### Test the connection
+
+Test your Custom Social Connection by clicking the **Try Connection** button located in the top right corner.
