Multi-Factor Authentication (MFA)
An extra layer beyond the password
Multi-factor authentication (MFA) adds a second layer of verification on top of the password: a temporary code generated by an app, a push notification to your phone, or a physical security key. Its value is simple but enormous: even if an attacker manages to steal or guess a password, they won't be able to access the account without that second factor, which normally only the legitimate owner has. Enabling MFA on email, social networks and above all bank accounts is one of the most effective individual measures against account theft, and today practically every major platform offers it for free. Preferring a code generated by an authenticator app, instead of one sent by SMS, offers additional protection against certain attacks that intercept text messages.
