# One-Time Verification

The one-time IAL2 verification flow enables end users to verify their identity by submitting two specified identity documents, a biometric, and an SSN.

### Prerequisites for Identity Verification

Before you begin verifying your identity, ensure the following:

* **Camera Access** — Make sure your device's camera has the necessary permissions enabled.
* **Selfie Check Tips** — Avoid glare in the background and remove any hats, glasses, or masks for a clear facial capture.
* **Document Preparation** — Have your identity documents ready before starting the verification process.

### Triggering the IAL2 Journey

Community administrators can use the following API to generate a verification URL and send the link to the user via email or phone:

```
/workflowapi/workflow_instance/tenant/{tenantId}/community/{communityId}/create
```

### Verifying Identity

End users can use the generated session URL to begin identity verification. Ensure you have the appropriate identity document ready for scanning and submission.

1. Click the session URL you received.
2. Read the instructions on the **Getting Started** screen and click **Start Verification**.
3. Grant the necessary camera permissions; click **Allow Camera Permissions**. On the **Allow Camera Permission** screen, the UI checks whether the device camera meets the required resolution of 1080×1920. If the requirement is not met, the UI redirects to the **QR Scan** screen, prompting the user to scan a QR code to continue the verification process on another device. 
4. On the **Selfie Check** screen, click **Begin Selfie**.
5. Position your face within the oval shown on the screen. When aligned properly, click **Take Selfie**.
6. After successfully capturing your selfie, prepare the required identity documents as displayed on the screen, then click **Continue** to proceed.
7. Read the instructions on the **Scan the Document** screen carefully, then click **Scan Document** to proceed.
8. Scan the front side of the first document. Once its authenticity is verified, the system prompts you to scan the next required document; click **Continue**.

   If the authenticity check fails, a **Verification not performed** message appears. Click **Try Again** to repeat the process. 
9. As an additional verification step, you are prompted to enter your Social Security Number (SSN). Enter the SSN and click **Continue** to proceed.

Upon successful verification, the UI confirms that your identity has been successfully verified and displays a list of the documents used during the verification process.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.1kosmos.com/identity-verification/ial2-verification/one-time-verification.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
