TL;DR: FIDO2 authentication replaces shared password reliance with public-key challenge response, but its security still depends on device lifecycle, loss handling, and user adoption, according to Axiad. The passwordless case is stronger than the passwordless rollout unless identity teams govern devices as first-class authenticators, not just login convenience.
Editorial analysis by NHI Mgmt Group, based on content published by Axiad: “What is FIDO2 Authentication and How Does It Work?”.
Key questions
Q: What breaks when passwordless access is added without governance changes?
A: The main failure is that organisations replace one authentication step but leave the same access model in place.
Q: Why does using FIDO2 in physical access control reduce password risk?
A: FIDO2 reduces password risk because it replaces reusable secrets with cryptographic authentication.
Q: How should IAM teams handle a lost FIDO2 authenticator?
A: Treat a lost authenticator as a credential incident, not a minor support ticket.
Practitioner guidance
- Define authenticator lifecycle ownership Assign clear ownership for enrollment, replacement, suspension, and revocation of FIDO2 devices so the authenticator is treated as a managed identity object.
- Build lost-device response workflows Document the steps for disabling a lost or stolen device, restoring access, and preventing weak fallback methods from becoming the default recovery path.
- Test passwordless recovery paths Walk through registration, backup factor use, and help desk recovery with real users to see where workarounds or bypasses appear.
Bottom line: FIDO2 removes reusable passwords from the authentication flow, but it shifts the core risk to the device that carries the private key.

Passwordless authentication shifts the control point, it does not remove identity governance. FIDO2 reduces reliance on shared secrets, but the real security boundary moves to the device that holds the private key and the process that governs its lifecycle. That means the programme now depends on enrollment, device replacement, revocation, and recovery discipline. Practitioners should treat the authenticator as the unit of control, not the login prompt.
A question worth separating out:
Q: What is the difference between passwordless authentication and credential governance?
A: Passwordless authentication is the method of proving identity without passwords. Credential governance is the operational control over how those credentials are created, updated, recovered, and retired. Organisations need both, because a strong authentication method can still be undermined by weak lifecycle management.
