TL;DR: FIDO2 strengthens user authentication with phishing-resistant credentials, but it does not cover machines, email signing, or document signing, according to Axiad’s analysis. The practical issue is not password replacement alone, but closing the authentication gaps that remain across human, machine, and interaction identity.
Editorial analysis by NHI Mgmt Group, based on content published by Axiad: “PKI and FIDO2: The Dynamic Duo of Authentication”.
By the numbers:
- 87% of large organizations already have adopted MFA solutions.
- 75% of IT leaders plan to increase MFA spending in the next year.
Key questions
Q: How should security teams combine FIDO2 and PKI without creating overlap?
A: Use FIDO2 for strong human authentication and PKI for machine identities, email signing, encryption, and document trust.
Q: Why do passwordless programmes still leave identity risk behind?
A: Because passwordless adoption usually covers the easiest systems first, while legacy apps, shadow IT, and recovery workflows still rely on human-created credentials.
Q: When should organisations add PKI to a passwordless strategy?
A: Add PKI when the environment depends on machine identity, signed communications, or document authenticity in addition to human login.
Practitioner guidance
- Define identity subjects separately Map where your programme authenticates humans, devices, services, email, and documents, then assign the assurance method each subject actually needs.
- Use FIDO2 for interactive user access Apply phishing-resistant authentication to workforce sign-in where the primary requirement is strong human login, not machine or content assurance.
- Use PKI for machine and content trust Issue certificates for devices, applications, email signing, and document signing so non-human and transactional identities are cryptographically verifiable.
Bottom line: FIDO2 strengthens user authentication, but it does not by itself secure every identity subject or trust workflow in the enterprise.

Authentication completeness, not password replacement, is the real governance problem: This article shows that organisations often mistake passwordless login for full identity coverage. FIDO2 can harden user sign-in, but it does not resolve machine identity, signed communications, or document trust. The implication is that IAM programmes must define what each identity subject is actually proving, not just whether a password has been removed.
A few things that frame the scale:
- 48% of organisations cite cloud-based services as a driver for PKI deployment, according to the 2023 State of Machine Identity Management report.
A question worth separating out:
Q: What should IAM teams review after rolling out FIDO2?
A: They should review whether the new login model has left certificate use cases, device authentication, or signed email outside governance. A successful rollout can still leave blind spots if machine and content trust were never mapped. The review should focus on identity subjects, lifecycle ownership, and assurance coverage.
