### Onfido

Onfido (Entrust) provides document and biometric verification through [Onfido Studio](https://documentation.identity.entrust.com/) workflows. Authsignal uses Onfido's authentication pattern, which relies on two distinct workflows: an enrollment workflow that captures the user's biometric, and an authentication workflow that re-verifies the user against the stored biometric.

<Info>
  Onfido is enabled as part of a paid subscription. Contact your [Authsignal account manager](mailto:support@authsignal.com) to have it added to your plan.
</Info>

#### Prerequisites

In your Onfido (Entrust) Dashboard, you'll need:

* An **API token** issued for your Onfido data region (EU, US, or CA).
* An activated **enrollment workflow** (Document & Motion) that enrolls the user's biometric.
* An activated **authentication workflow** that re-verifies the user against the stored biometric.

You configure both workflows in Onfido Studio. Note the workflow ID of each, since you'll need them during setup.

#### Enable Onfido in the Portal

1. Navigate to the [Authenticators section](https://portal.authsignal.com/organisations/tenants/authenticators) in your Authsignal Portal
2. Find **Onfido** in the biometric authenticators list
3. Click **Setup Onfido**
4. Select your **Region**. This must match the region your API token was issued for.
5. Enter your **API token**.
6. Copy the **Webhook URL** shown in the Portal. In your Onfido dashboard, create a webhook for the `workflow_run.completed` event pointing at this URL, then paste the **webhook signing token** that Onfido shows back into the Portal.
7. Enter your **Enrollment workflow** ID and **Authentication workflow** ID.
8. Click **Activate Onfido**.

## Implementation

Once you've configured your preferred biometric provider in the Portal, you can use it like any other Authsignal authenticator:

* **Track actions** that require biometric verification using our [Server SDK](/sdks/server/actions#track-action) or [Server API](/api-reference/server-api/track-action)
* **Launch the pre-built UI** to present the biometric verification challenge to users
* **Validate challenges** on your backend to confirm successful verification

The biometric verification flow integrates seamlessly with Authsignal's [rules engine](/actions-rules/rules/getting-started), allowing you to trigger biometric authentication based on risk factors, user behavior, or specific business requirements.
