Knowledge-Based Authentication
An authentication method that verifies users based on personal knowledge, such as security questions.
Understanding:
KBA is an authentication method that verifies a user’s identity based on knowledge-based questions (e.g., "What was your first pet's name?").
Common Applications and Use Cases:
Account Recovery – Used when users forget their passwords.
Online Banking & E-Commerce – Adds an extra layer of security.
Fraud Prevention – Used in financial transactions.
Best Practices and Security Considerations:
Avoid Easily Guessable Questions – Prevent social engineering attacks.
Use Multi-Factor Authentication (MFA) – Reduces reliance on KBA.
Rotate Security Questions Periodically – Enhances security.
