SafeSchools Internet Security Practice Test

Two-factor authentication (2FA) is designed specifically to enhance security by requiring two forms of verification before granting access to an account or system. This typically involves something the user knows (like a password) and something the user has (like a code sent to a mobile device). By implementing this method, even if one factor, such as a password, is compromised, an attacker would still need the second factor to gain access. This significantly reduces the risk of unauthorized access and helps ensure that the user's information remains protected against various cyber threats.
