What is knowledge-based authentication?
Knowledge-based authentication (KBA) is a security process that verifies a user's identity by asking them to answer specific questions.
How does KBA work in practice?
In practice, KBA requires users to provide answers to questions only they should know, like their mother's maiden name or the name of their first pet.
What are the pros and cons of using KBA?
Pros include enhanced security and ease of use, while cons involve potential for social engineering attacks and difficulty in remembering answers.
Are there alternatives to KBA?
Yes, alternatives include biometric authentication, two-factor authentication, and security tokens.
