Advantages of FIDO2 and Passkeys for the Workforce
TL;DR · the short version
Deploying FIDO2 and passkeys for the workforce delivers on three axes at once. Security: origin-bound credentials are phishing-resistant, blocking the phished-credential and MFA-relay attacks behind most account takeovers. Productivity: passkey sign-in is faster than a password plus OTP, with fewer failed logins. Cost: fewer password resets and takeover incidents cut help-desk and IR load, and phishing-resistant MFA can lower cyber-insurance friction. Realising it takes removing weaker fallbacks and registering more than one authenticator per user.
Most security controls trade user experience for protection. FIDO2 and passkeys are the unusual case that improves both — which is why rolling them out to the workforce is one of the highest-return identity projects available. The benefits land on three axes at once.
Security
Passkeys and FIDO2 keys are origin-bound, so they are phishing-resistant: a credential cannot be released on a lookalike domain or relayed by an adversary-in-the-middle kit. There is no shared secret sitting in a database to breach. Together that removes the phished-credential and MFA-relay attacks behind most account takeovers.
Productivity
Signing in with a fingerprint, face or device PIN is faster than typing a password plus a one-time code — and there is nothing to forget, no code to copy, and far fewer failed logins. Login time and reset cycles both drop, which is why adoption is usually high once employees try it.
Cost
Password resets are a large share of help-desk tickets, and account-takeover incidents are expensive to investigate. Phishing-resistant, secret-free sign-in reduces both, cutting support and IR load. Phishing-resistant MFA can also ease cyber-insurance requirements.
Realising the benefits
Two steps decide whether you actually get the upside. Register at least two authenticators per user (a platform passkey plus a roaming key) to remove lockout risk, and remove weaker fallbacks (SMS/OTP) on hardened accounts — the security benefit only holds if attackers cannot fall back to the phishable path.
FIDO2 advantages over SMS, OTP and push MFA
The key advantage of FIDO2 over other workforce MFA is that it resists phishing and relay by design. The credential is bound to the real site's origin, so there is nothing a user can be tricked into typing or approving on a fake page.
- Vs SMS codes: one-time codes sent by SMS can be phished, relayed in real time or intercepted through SIM swapping. FIDO2 has no code to hand over.
- Vs authenticator-app codes (TOTP): a six-digit code can be typed into a lookalike site and replayed by an adversary-in-the-middle kit while it is still valid. A FIDO2 authenticator only signs for the genuine origin.
- Vs push approvals: push prompts are open to MFA fatigue (prompt bombing), where a user approves an attacker's sign-in out of habit. FIDO2 needs the user's own gesture on their own device, for the legitimate site.
- Vs passwords: the private key never leaves the authenticator and the server stores only a public key, so a server-side breach yields nothing an attacker can reuse.
This is why phishing-resistant MFA guidance, including CISA's, treats FIDO2/WebAuthn as the strongest widely available option for the workforce.

How to assess FIDO2 readiness
Before you enable anything, run a short readiness assessment:
- Check support. Confirm your identity provider and critical applications accept WebAuthn, and inventory the browsers and devices in use.
- Choose authenticators by population. Hardware security keys give the strongest assurance for administrators, finance and other high-risk users. Synced passkeys scale to the wider workforce with less friction.
- Design recovery first. Register at least two authenticators per account and keep a reset path that is itself phishing-resistant, with no SMS fallback.
- Pick the first accounts. Protect privileged and high-value accounts first, pilot with a small group, measure enrollment and support load, then widen.

Frequently asked questions
Main benefits? Stronger security (phishing-resistant, no shared secret), better productivity (faster sign-in, fewer resets), lower cost (less help-desk/IR load).
Easier for employees? Generally yes — biometric/PIN sign-in beats password-plus-OTP and cuts failed logins.
Reduce support cost? Yes — fewer password resets and takeovers; can ease insurance friction.
What's required? Two authenticators per user and removing phishable fallbacks on hardened accounts.
Frequently asked questions
What are the advantages of FIDO2 over SMS or app-based MFA?
FIDO2 credentials are bound to the real site's origin, so they cannot be phished, typed into a lookalike page or relayed by an adversary-in-the-middle kit. SMS and authenticator-app codes can be, and push approvals are open to MFA-fatigue attacks. FIDO2 also leaves no shared secret on the server, because the server stores only a public key.
How does FIDO2 improve workforce security?
FIDO2 (and passkeys) improve workforce security by replacing phishable secrets with origin-bound credentials: the credential is cryptographically tied to the real site, so it cannot be released on a lookalike domain or relayed by an adversary-in-the-middle kit, and there is no shared secret in a database to steal. That removes the phished-credential and MFA-relay attacks behind most account takeovers. You realise the benefit by registering at least two authenticators per user and removing weaker SMS/OTP fallbacks on the accounts you have hardened.
How do FIDO2 passkeys work for ministry or government employees?
The same way they work for any workforce: a passkey is a FIDO2/WebAuthn credential unlocked by a fingerprint, face or device PIN and bound to the real sign-in origin, so it is phishing-resistant and has no shared secret to breach. For government and ministry staff — often a higher-value target — the usual pattern is synced passkeys for the general workforce plus device-bound hardware security keys for administrators and privileged accounts, two authenticators registered per user to avoid lockout, and phishable fallbacks removed on hardened accounts.
What are the main benefits of FIDO2 for the workforce?
Three at once: stronger security (phishing-resistant, origin-bound credentials with no shared secret to steal, which removes the most common account-takeover paths), better productivity (faster sign-in than password-plus-OTP, fewer failed logins, no codes to copy), and lower cost (fewer password resets and account-takeover incidents reduce help-desk and incident-response load). Few security controls improve security and user experience simultaneously; passkeys do.
Are passkeys actually easier for employees?
Generally yes. Signing in with a passkey — a fingerprint, face, or device PIN — is faster than typing a password and then a one-time code, and it removes the friction of forgotten passwords, expired codes, and reset cycles. Because there is nothing to remember or type, both login time and failed-login rates typically drop, which is part of why adoption tends to be high once users try it.
Do passkeys reduce help-desk and support costs?
They can. A large share of help-desk tickets are password resets, and account-takeover incidents are expensive to investigate. Phishing-resistant, memorised-secret-free sign-in reduces both, lowering support and incident-response load over time. Phishing-resistant MFA can also reduce friction with cyber-insurers, who increasingly expect it.
What is required to realise the benefits?
Two things beyond deployment. First, register at least two authenticators per user (for example a platform passkey plus a roaming security key) so there is no lockout risk. Second — the step organisations most often skip — remove weaker, phishable fallbacks (SMS/OTP) on the accounts you have hardened, because the security benefit only holds if attackers cannot fall back to the weak path.
