Nerve Center: Tech Tip 1: MFA Tune‑Up: Make Sure It’s Working Properly
Multi-factor authentication (MFA) is one of your organization’s strongest lines of defense against account compromise, but only if it’s working correctly. As we close out the year, now is the perfect time to run a “MFA health check” to ensure nobody is stuck, locked out, or exposed.
Why You Need to Audit Your MFA Now
Many companies enable MFA and then assume the job is done. But several common issues can weaken its effectiveness:
- Lost or unstored backup codes. Without backup or recovery codes stored safely, users can get locked out if they lose their device.
- Desynchronized authenticator apps. Devices may drift out of sync, especially if not used regularly, making recovery difficult.
- Inactive or orphaned devices. Old phones, tablets, or computers may still be authorized for MFA, giving attackers a potential foothold.
- Weaker factors still in use. Using SMS-based MFA or email codes remains more vulnerable to attacks like SIM swapping or phishing.
These gaps mean that simply “having” MFA doesn’t guarantee it’s protecting you effectively.
Recommended Year-End MFA Check: A Simple Checklist
- Audit all registered MFA devices. Go through every user’s MFA settings and remove any unused or missing devices.
- Verify backup or recovery codes. Make sure every user has valid backup codes stored in a secure place (e.g., a password manager, secure file, or printed copy in a safe).
- Upgrade to phishing-resistant MFA. Wherever possible, migrate to stronger methods, FIDO2 security keys, passkeys, or biometric-based authenticators. These offer much greater protection than SMS or email.
- Test your workflows. Run through typical login flows and recovery flows in a test environment to confirm that MFA works, even when things go wrong.
- Review privileged accounts. Double check that MFA is enforced on high-risk accounts (admins, finance, remote access) and that recovery options are well defined for them.
Best Practices to Sustain MFA Strength
- Plan for device loss: Make sure users know how to recover using backup codes, alternate devices, or helpdesk support.
- Avoid MFA fatigue: Implement logic or policies to limit repeated prompts, especially for trusted devices.
- Log and monitor: Track every MFA challenge, success, failure, and recovery event. Unusual patterns might signal an attack or misconfiguration.
- Train your team: Educate your users on how to use recovery codes, change devices safely, and report MFA problems promptly.
