Quizplus · Accepted Answer

The most secure type of authentication is a combination of something the user knows (like a password), something the user has (like a smart card or token), and something that is part of the user (like a fingerprint or voice signature). This multi-factor approach significantly enhances security by requiring multiple forms of verification.
