Multi-Factor Authentication (MFA) is one of the most effective defenses against account takeover. Even if a password is leaked or phished, requiring a second factor such as a code from an authenticator app, biometric confirmation, or hardware token adds a strong barrier. MFA significantly reduces the risk of unauthorized access, protects sensitive data, and improves overall account security.
Some MFA methods (e.g. SMS) are vulnerable to interception or SIM-swapping, so using more secure alternatives (authenticator apps, hardware tokens) or phishing-resistant methods is preferable.
