Two-factor authentication (2FA) enhances security measures by requiring two forms of verification to grant access to an account. Typically, 2FA combines something the user knows, like a password, with something the user possesses, such as a smartphone or a security token. This layered approach reduces the risk of unauthorized access, as compromising one factor alone is insufficient for breaching security. By implementing 2FA, organizations strengthen their defense against hacking attempts, phishing, and other cyber threats, fostering trust and protecting sensitive information.
