Two-Factor Authentication (2FA) is an important tool for protecting sensitive data. It is a security measure that requires two different authentication factors (methods) in order to access an account. The first factor is typically something the user knows, such as a password, and the second factor is often something the user has, such as a physical token or a code sent to their mobile device. With two-factor authentication, an attacker needs more than just the user’s password to gain access, making it much more difficult for a hacker to gain access to a user’s account. 2FA is becoming increasingly popular as people become more aware of the importance of online security, and it is a great way to help protect sensitive data and accounts.
