Implementing multi-factor authentication enhances security by requiring users to provide additional forms of verification, such as a code from a mobile device or biometric data, in addition to a password. This makes it more difficult for unauthorized users to gain access, even if they have obtained a user's password. Enforcing password complexity, installing antivirus software, and requiring background checks, while important, do not provide the additional layer of security that multi-factor authentication offers against unauthorized connection attempts.
