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.
Editorial analysis by NHI Mgmt Group, based on content published by Frontegg: “FIDO2 Security Keys: A Practical Guide”.
By the numbers:
- 74% of consumers are now familiar with passkeys, according to Frontegg.
- More than 35% of people experienced account compromises due to password vulnerabilities in the previous year, according to Frontegg.
Key questions
Q: What breaks when passwords are replaced with FIDO2 security keys?
A: The main break is the shared-secret model.
Q: Why do FIDO2 and passkeys reduce phishing risk more effectively than OTP codes?
A: FIDO2 binds the authentication response to the relying-party origin, so a lookalike site cannot reuse the assertion.
Q: How should IAM teams decide between platform and roaming authenticators?
A: Use platform authenticators for tightly controlled, single-device workflows and roaming authenticators when users move between devices, travel, or share workstations.
Practitioner guidance
- Define where passwordless is mandatory Map high-risk accounts, such as admin profiles and production access, to device-bound FIDO2 keys and require local user verification for those accounts.
- Register backup keys at enrolment Require at least two enrolled keys for each account so users can recover access without falling back to weaker reset channels or shared support workflows.
- Set custody rules for roaming keys Store spare keys in controlled locations, track assigned users and serial numbers, and revoke lost or stolen keys through a written recovery process.
Bottom line: FIDO2 security keys reduce credential theft by replacing passwords with device-bound cryptographic authentication.

FIDO2 shifts IAM away from shared-secret governance: Passwordless authentication is not just another login option, it is a different trust model. Once the private key never leaves the authenticator, phishing and database replay stop being the main control problem and identity assurance moves to device custody and local verification. For IAM teams, the practical implication is that authentication policy must be designed around cryptographic possession, not secret memorisation.
A question worth separating out:
Q: When should organisations require PIN or biometric verification with a security key?
A: Require PIN or biometric verification for accounts where physical theft would create unacceptable risk, especially administrative or sensitive business systems. A tap-only key is still stronger than a password, but local verification adds another layer that limits misuse if the device is lost or borrowed.
