The significance of two-factor authentication (2FA) lies in its ability to enhance security by requiring two forms of identity verification from users. Typically, 2FA combines something the user knows (like a password) with something they have (like a mobile device). This layered approach makes unauthorized access considerably more challenging, protecting sensitive information and accounts from potential breaches. As cybersecurity threats continue to evolve, implementing 2FA is an essential measure for individuals and organizations to secure their digital assets more effectively.
