What is the main benefit of two-factor authentication?

The main benefit of two-factor authentication (2FA) is that it significantly enhances security by requiring two forms of identification from the user during the login process. This typically involves a combination of something the user knows, like a password, and something the user has, such as a smartphone app that generates a time-sensitive code or a hardware security token.

This dual-layer approach makes it much more difficult for unauthorized users to gain access to sensitive information or accounts, even if they manage to obtain the password. By implementing 2FA, organizations are able to protect against various types of attacks, such as phishing, where attackers try to steal credentials. The requirement of a second authentication factor acts as a critical safeguard against potential breaches, thereby increasing overall security for users and systems.

Other options may include elements related to security or login processes, but they do not represent the core advantage provided by two-factor authentication, which is fundamentally about enhancing protection against unauthorized access.
