Multi-factor authentication (MFA) is one of the single most effective controls a business can deploy — but a growing body of incident reporting makes an uncomfortable point clear: attackers are increasingly logging in, not breaking in, and they've developed reliable ways to get past weaker forms of MFA.
How MFA gets bypassed
Without going into a playbook, the common routes are well understood: real-time phishing pages that relay your code as you type it, "MFA fatigue" where users are bombarded with approval prompts until one is accepted, and the theft of session tokens that let an attacker skip authentication entirely.
How to make your MFA hold up
- Prefer phishing-resistant MFA (passkeys / FIDO2 hardware keys) over SMS codes where you can.
- Switch on number-matching and limit repeated push prompts to defeat fatigue attacks.
- Use conditional access — factor in device health, location and risk, not just the password-plus-code.
- Protect sessions, with shorter lifetimes and re-authentication for sensitive actions.
MFA absolutely remains a must-have — the goal is to deploy the right kind, configured properly. We design and manage exactly this for clients. Ask us to review your sign-in security.
