Multi-factor authentication is now table stakes, but the way you implement it matters. Attackers have moved beyond simple password spraying to real-time phishing, session hijacking, and social engineering that targets your MFA process itself. In 2026, the safest MFA is phishing-resistant and tied to device trust, not just a one-time code.
TL;DR
Replace SMS with phishing-resistant factors, enforce conditional access, and document secure recovery options.
Start by retiring weak factors
SMS codes and email links are still common, but they are also the easiest to phish or intercept. If you are still using them for admin roles, finance, or any system with sensitive data, you are leaving a gap attackers know how to exploit.
- Replace SMS with app-based approvals or time-based codes.
- Move high-risk users to FIDO2 security keys or passkeys.
- Disable legacy protocols that bypass modern MFA controls.
Adopt passkeys where possible
Passkeys (FIDO2) are built to stop phishing by design. The credential is bound to the device and the user, and it only works on the legitimate site. Many major platforms now support passkeys for both staff and admins, and they reduce help desk time because there is nothing to type or reset.
Layer conditional access and device trust
MFA should not be a simple yes or no decision. Use conditional access to require stronger factors for high-risk logins, and block access when the device is unmanaged or the sign-in comes from a new location. This is especially important for remote work and BYOD scenarios.
Plan for recovery and continuity
When a device is lost or a user is locked out, recovery needs to be secure but fast. Document your recovery flow and test it quarterly. Keep backup methods that are not as strong but are tightly controlled, such as one-time recovery codes stored in a secure vault.
A simple rollout plan
If you want to modernize MFA without disruption, start with a pilot group and expand in phases. Train users on what to expect, show them how to spot MFA fatigue prompts, and set clear rules for approvals. A one-week pilot can uncover 90 percent of rollout issues before you go company-wide.
Done right, MFA becomes a quiet, reliable security layer instead of a daily frustration. If you need help mapping your systems to the right MFA types, we can review your stack and build a phased plan that balances security with user experience.
