Multi-factor authentication is still one of the highest-impact security controls you can deploy — but it is not a force field. Attackers have adapted, and weaker forms of MFA are now routinely bypassed. Knowing the difference matters.
How attackers beat MFA- Real-time phishing proxies sit between you and the real site, relaying your password and one-time code as you type them
- MFA fatigue (push-bombing) spams approval prompts until a tired user taps allow
- SIM swapping hijacks SMS codes by taking over your phone number
The fix is not to drop MFA but to upgrade it. Prefer passkeys or hardware security keys (FIDO2), which are bound to the real domain and cannot be relayed by a proxy. Where you must use app-based MFA, switch from one-tap approval to number matching, and avoid SMS for anything sensitive.
Beyond the login boxPair strong MFA with least-privilege access and sign-in monitoring — impossible-travel and new-device alerts — so a single stolen session cannot quietly become a full account takeover.
