# Two-Factor Authentication (2FA)

Two-Factor Authentication adds a critical extra layer of security to your MessageFlow account. When 2FA is enabled, logging in requires two pieces of evidence to prove your identity: your password and a time-sensitive code generated by an authenticator app on your phone, SMS code or a hardware key. We highly recommend enabling 2FA to significantly enhance your account's protection against unauthorized access, even if your password becomes compromised.
