Two-Factor Authentication (2FA) significantly enhances the security of user accounts by requiring a second form of verification in addition to the traditional password. This additional layer makes it much harder for attackers to gain unauthorized access, even if they manage to obtain a user’s password.
The security improvement from enabling 2FA can be quantified by considering the reduction in the number of potential attack vectors. Without 2FA, an attacker only needs to compromise one factor (the password). With 2FA, they must successfully breach both the password and a second factor, such as a code sent to a mobile device or generated by an authenticator app.
