## Set up Silent Network Authentication in the RiskOS™ Dashboard

Socure Silent Network Authentication confirms in-session possession of a mobile phone number using real-time mobile operator signals. When SNA is unavailable, One-Time Passcode (OTP) serves as a configurable fallback.

### Step 1 - Provisioning

Your account must be provisioned for the `SilentNetworkAuth` feature. Contact your Socure account team for provisioning.

### Step 2 - Add Socure Silent Network Authentication enrichment

1. In the RiskOS™ Dashboard, go to **Workflows** and create a new workflow or open an existing one.
2. On the workflow canvas, select the **plus (+)** icon.
3. Add an **Enrichment** step and select **SocureSNA**.

### Step 3 - Configure Conditions

Connect the SocureSNA enrichment to a **Condition** to evaluate the result of the phone number possession check. In this example, we’ve renamed the condition to **Phone Verified**.

- The result of the SNA check is stored in the variable: `socure_sna_response.status`
- Click on the **Phone Verified** condition and choose `socure_sna_response.status` from the Variable dropdown.
- Choose **string contains** as the operator.
- Enter `approved` as the value.

Now, when the Silent Network Authentication check confirms that the user-supplied phone number matches the SIM-registered number, the condition will evaluate to true, and your workflow will proceed.

### Step 4 - Handle Phone Number Mismatch

If the **Phone Verified** condition is false:
- Add another condition on the false branch named **Phone Number Mismatch**.
- Configure it to check if `socure_sna_response.status` contains `phoneNumberMismatch`.

If a mismatch is confirmed, reject the transaction (user does not have possession of the phone number). Alternatively, route to manual review or handle according to your policies.

### Step 5 - Fallback to One-Time Passcode

If no mismatch is confirmed and SNA cannot complete (for example, unsupported carrier, no SIM, or no cellular connectivity), fall back to an OTP check to verify phone number possession. This ensures continuity and coverage for all users while maintaining a layered security approach.

## Example workflow outcomes

- **Accepted** → Workflow continues normally.
- **Phone Number Mismatch** → Reject or review transaction.
- **Unsupported / Error** → Fall back to OTP.
