The Prove Connector provides connectivity with [Prove](https://www.entrust.com/products/identity-verification), designed to help you accelerate your lending and onboarding process by prefilling end user personal information. It only requires the user's phone number, or their SSN last 4 digits, or date of birth.

*This feature is only available in the United States.*
