Phishing-resistant MFA on admin accounts is no longer a nice-to-have for cyber insurance underwriting. It’s close to a baseline requirement, and several carriers are starting to ask the same question about the rest of the workforce too. A coverage gap that used to be a security-team problem is now something that can affect whether a claim gets paid at all.
The questionnaire changed, not just the requirement
Cyber insurance applications used to run around a dozen questions. In 2026, questionnaires commonly run past 80 (InsurableIT, 2026 cyber insurance questionnaire guidance). The bigger change isn’t the length. It’s what the questions are actually asking.
Older questionnaires asked whether a control existed. Current ones ask whether it’s enforced everywhere it needs to be, and whether that was true at the moment an incident happened. Carriers are increasingly writing MFA warranties directly into policy language, which means an attestation that doesn’t match reality at the time of a breach can be treated as material misrepresentation, and used to deny a claim.
The questionnaire isn’t asking if you have a control. It’s asking if you can prove it, everywhere, all the time.
What carriers are actually checking for
Coverage requirements in 2026 tend to focus on a consistent list: every privileged or administrative account, every remote access path (VPN, RDP, SSH, jump hosts), every email account, and every cloud admin console. Carriers writing limits above $1 million increasingly ask specifically whether admin accounts use hardware-backed security keys rather than software-based one-time codes, and that answer affects both pricing and whether coverage is offered at all (GMA CPA, Cyber Insurance in 2026).
Phishing-resistant MFA for all admins has moved from best practice to expected. Phishing-resistant MFA for the full employee population is newer territory, but it’s starting to show up as a premium-discount question rather than a hard requirement, and a handful of carriers already offer explicit discounts for organization-wide FIDO2-grade authentication (goleadingit, MFA Requirements for Cyber Insurance 2026).
Underwriting has also gotten harder to bluff. Many carriers now supplement the questionnaire with outside-in technical scans and, in some cases, mid-term validation instead of waiting until renewal to check anything.
Where the YubiKey coverage gap turns into an insurance problem
Most companies that deploy hardware tokens only reach 15 to 30 percent of employees, the executives, engineers, and finance staff seen as highest-risk. The remaining 70 to 85 percent typically run on weaker authentication (see the full coverage-gap breakdown).
That’s a security gap on its own. Under a 2026 questionnaire, it’s also a documentation problem. If a company attests to phishing-resistant MFA and a breach later happens through an unprotected account outside that 15 to 30 percent, the gap between what was claimed and what was actually enforced is precisely the scenario carriers are underwriting against.
Closing that gap by badging every employee with a physical hardware key is the obvious answer and also the expensive one: at $50 to $80 per device, a 10,000-person company is looking at $500,000 to $800,000 before logistics and replacement costs. Extending phishing-resistant, hardware-grade authentication through the SIM employees already carry closes the same gap without that price tag, and without the rollout timeline.
A self-check before your next renewal
Before a questionnaire or a broker call surfaces this as a problem, it’s worth mapping it yourself:
Start by identifying every privileged account, remote access path, email account, and cloud admin console in scope, then check whether phishing-resistant MFA is actually enforced on all of them, not just attested to. Extend that same check to the broader employee population, since that’s the direction the questionnaires are heading. Wherever a gap turns up, whether it’s an unprotected employee tier or a fallback path that quietly reverts to SMS OTP, that’s the specific thing to fix before renewal, not after a claim.
Unibeam runs this as a 30-day coverage audit at no cost: map current coverage, pilot non-covered employees on hardware-grade SIM authentication, and get a full report showing authentication strength across every employee tier. Reach out at [email protected] or visit unibeam.com.

FAQ
Phishing-resistant MFA for privileged and administrative accounts is close to a baseline requirement across most carriers in 2026. Extending it to the entire employee population isn’t universally required yet, but it’s starting to appear as a factor in premium discounts, and the direction of travel points toward broader enforcement expectations.
Carriers generally mean hardware-backed or cryptographic methods, such as FIDO2 security keys or SIM-anchored authentication, as opposed to SMS one-time codes or app-based push notifications, which remain vulnerable to phishing and SIM-swap style attacks.
Some carriers now write MFA requirements into policy language as a warranty. If a company attested to enforcement that wasn’t actually in place at the time of an incident, that mismatch can be treated as material misrepresentation and used as grounds to deny the claim.
Map which accounts and employees currently lack phishing-resistant MFA, then extend hardware-grade authentication to that group. Doing this through SIM-anchored credentials instead of physical hardware tokens avoids the procurement and distribution timeline a full hardware rollout would require.
