Two-factor authentication (2FA) requires users to verify their identity usingtwo independent authentication factorsfrom different categories, such as something you know and something you have.
The purpose of 2FA is to strengthen authentication security and reduce the risk of unauthorized access. Even if one factor is compromised, the attacker cannot authenticate without the second factor.
2FA is a subset of multi-factor authentication and is strongly recommended by modern security standards, particularly for remote access, cloud services, and privileged accounts.
