Which authentication method verifies a user's identity using something they know, such as a password?

  • Biometric Authentication
  • Knowledge-Based Authentication
  • Multi-Factor Authentication

Knowledge-Based Authentication verifies a user's identity based on something they know, such as a password, PIN, or passphrase.

However, it is important for users to choose strong passwords and for systems to implement secure password storage mechanisms to prevent unauthorized access.
