Which of the following is true about two-factor authentication (2FA)?

Two-factor authentication (2FA) adds an extra layer of security for user accounts by requiring two different forms of verification before granting access. This typically involves something the user knows (like a password) and something they have (like a text message code, authentication app code, or hardware token). This additional step significantly increases the security of accounts, making it much harder for unauthorized users to gain access, even if they manage to obtain the password.

The implementation of 2FA helps protect sensitive data and enhance overall cybersecurity posture, as it mitigates risks associated with stolen credentials. By requiring two forms of verification, 2FA not only strengthens account security but also instills greater user confidence in protecting their personal information from potential breaches.
