What is Knowledge-Based Authentication?
Knowledge-based authentication (KBA) is a premium authentication method that secures a high-level verification of identity.
The authentication process challenges the recipient to answer a few questions generated from public and private data such as marketing data, credit reports, or transaction history.
The knowledge needed to answer the questions is not available in a person’s wallet (some companies call them “out-of-wallet questions”) making it difficult for anyone other than the actual identity owner to know the answer and obtain access to secured information.
Example questions:
- Select the correct house number of the address you shared with {some name}
- Which of the following cars have you owned
- In which of the following cities have you attended college
- From whom did you purchase the property {some address}
- Which age range matches the age of {some name}
