What is two-factor authentication?
Quick answer
Two-factor authentication (2FA) adds an extra layer of security by requiring not only a password and username but also something that only the user has on them, such as a physical token or a mobile app code.
Two-factor authentication enhances account security by requiring two forms of verification, making unauthorized access significantly harder.
