What does two-factor authentication enhance?

Two-factor authentication (2FA) enhances account security by requiring users to provide two different forms of verification before gaining access to their accounts. This typically involves something the user knows (like a password) and something the user has (like a smartphone app that generates a one-time code or a physical token).

By implementing this additional layer of security, even if a malicious actor manages to obtain a user's password, they would still be unable to access the account without the second form of authentication. This significantly reduces the risk of unauthorized access, thereby protecting sensitive information and reducing the likelihood of account compromise. The increase in account security is crucial in today's digital environment, where data breaches and credential theft are prevalent.

While other factors like system performance and user convenience may be important, they do not directly relate to the primary purpose of 2FA, which is to bolster security measures.
