# 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>
