FIDO2 security keys: what changes for IAM and access governance?

TL;DR: FIDO2 security keys replace passwords with phishing-resistant cryptographic credentials that keep private keys on the device, support browser-based challenge response through WebAuthn and CTAP2, and reduce reuse and interception risk, according to Frontegg. For IAM teams, the shift is less about convenience and more about removing shared-secret assumptions from authentication design.

NHIMG editorial — based on content published by Frontegg: FIDO2 security keys and passwordless authentication

By the numbers:

• 74% of consumers now familiar with passkeys, and more than 35% experienced account compromises due to password vulnerabilities in the previous year.

Questions worth separating out

Q: How should organisations roll out FIDO2 security keys without breaking access recovery?

A: Start with two enrolled keys per user, defined revocation procedures, and a documented replacement process for lost devices.

Q: Why do FIDO2 security keys reduce phishing risk so effectively?

A: They replace shared secrets with a signed challenge that only the registered authenticator can complete.

Q: What do security teams get wrong about passwordless authentication?

A: They often treat the login method as the whole control and ignore enrolment, backup, and revocation.

Practitioner guidance

• Enrol at least two keys per account Register a primary and backup FIDO2 key from day one, and store the spare in a controlled location so access does not depend on one device or one person being available.
• Require PIN or biometric verification for privileged access Disallow touch-only mode for admin accounts, production access, and other high-risk systems so physical possession alone cannot complete authentication.
• Remove weak recovery paths from the authentication chain Review help-desk reset flows, emailed recovery links, SMS fallback, and legacy bypasses, because those paths often become the real compromise point after passwordless rollout.
