Knowledge-based Authentication, commonly referred to as KBA, is a method of authentication that seeks to prove the identity of someone accessing a service.
Proof uses secure third-party data sources to generate Knowledge-based Authentication (KBA) questions as the first part of Multi-Step Verification, an identity-verification method.
- Notarization: The methods available for verifying a signer's identity vary depending on the state in which the notary is commissioned. (The second part of Multi-Step Verification is Credential Analysis.)
- Proof Transaction: The methods used to verify a signer's identity are selected by the person or entity creating and sending the transaction.
KBA questions can be generated for anyone residing in the 50 United States or these three U.S. Territories: Puerto Rico, American Samoa, and U.S. Virgin Islands.
