Knowledge-based Authentication, commonly referred to as KBA, is a method of authentication that seeks to prove the identity of someone accessing a service.
Notarize uses secure third-party data sources to generate Knowledge-based Authentication (KBA) questions as the first part of Multi-Step Verification, an identity-proofing method. 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.)
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.
