Why is multi-factor authentication (MFA) recommended?

Multi-factor authentication (MFA) is recommended primarily because it adds an extra layer of security to the authentication process. By requiring two or more verification factors to gain access to a system, it significantly enhances the protection of sensitive information.

Typically, MFA combines something you know (like a password), something you have (like a security token or smartphone app), and something you are (like a fingerprint or facial recognition). This layered approach makes it much more challenging for unauthorized individuals to access accounts, as they would need to compromise multiple factors instead of just guessing or stealing a single password.

Having MFA in place is especially vital in an era where cyber threats are prevalent, as it helps deter attacks such as phishing and password reuse, thereby increasing overall cybersecurity posture. This makes MFA essential for safeguarding personal, organizational, and sensitive data.
