# Facematching

This step compares the user’s face across multiple sources to verify their identity. It is crucial for preventing identity fraud and ensuring the integrity of the verification process.

* Add `Face Matching` step into the flow canvas at the appropriate position in the flow.
* Click on `Face Matching` to open its configuration options:

<table data-header-hidden><thead><tr><th width="205.06640625"></th><th></th></tr></thead><tbody><tr><td><strong>Source Selection</strong></td><td>Choose minumum 2 sources for face matching, including the following:</td></tr><tr><td></td><td><strong>Document Photo:</strong> Use the photo from the uploaded document.</td></tr><tr><td></td><td><strong>Liveness Results:</strong> Use the captured image from the liveness check.</td></tr><tr><td></td><td><strong>Selfie:</strong> Use a selfie taken by the user.</td></tr><tr><td></td><td><strong>External Database:</strong> Use a photo from an external database.</td></tr><tr><td><strong>Verification Validity Period</strong></td><td>This setting defines how long a successful verification result remains valid. Enforce re-verification after a defined time window for security or compliance needs.</td></tr></tbody></table>

{% hint style="info" %}
**Minimum Requirement:** You must select at least two sources for face matching to ensure robust verification.\
To use data from another step (Document Scan, Liveness, or Selfie) in Facematching, add that step to the flow first. It will then become available in the list of options.

**Auto-Approval:** an Applicant is approved automatically, if face matching result is 85% or higher. Otherwise, the reviewer has to check the results and finish the verification process manually.&#x20;
