How to Strengthen Your Two-Factor Authentication Against Failures

Quick Summary

• Two-factor authentication (2FA) and multi-factor authentication (MFA) are methods to secure accounts using additional checkpoints beyond a password, such as PINs, codes from authenticator apps, or biometric IDs.
• MFA provides greater security then 2FA by combining autonomous factors rather than relying on variations of the same knowledge-based credentials.
• Despite it’s advantages, MFA can still be compromised through adversary-in-the-middle phishing attacks, where hackers intercept authentication codes via fake proxy sites.
• Phishing-as-a-service toolkits make these attacks more accessible to malicious actors.
• More secure MFA options include WebAuthn credentials or physical security keys like Yubikey, which resist phishing by tying authentication to specific devices and URLs.
• Users are advised to adopt stronger MFA techniques and remain vigilant for phishing scams that exploit urgency and fear.
