What does "KBA" stand for in identity verification?

The term "KBA" stands for Knowledge-Based Authentication, which is a crucial method used in identity verification processes. This technique relies on information that is known only to the individual whose identity needs to be verified. This can include personal questions or facts, such as prior addresses, specific account details, or other unique identifiers that a legitimate user would know, but that would be challenging for an unauthorized person to guess or ascertain.

Using KBA helps in ensuring a higher level of security by adding an additional layer of authentication beyond just user credentials like passwords. It plays an important role in various sectors, including banking, finance, and e-commerce, where confirming a person's identity is essential to prevent fraud and protect sensitive information.

The other options, while they may sound plausible, do not correlate with the established term used in identity verification practices. This specificity makes Knowledge-Based Authentication the standout correct choice.
