TL;DR: Passwordless authentication is moving into the mainstream, with over a third of organisations planning to adopt or continue using it in the next one to three years, according to Descope. The key governance issue is not whether WebAuthn or FIDO2 is more secure in isolation, but how browser, device, and lifecycle controls fit together across human identity programmes.
Editorial analysis by NHI Mgmt Group, based on content published by Descope: “WebAuthn vs FIDO2: Understanding the Differences”.
By the numbers:
- No less than 85% of all devices worldwide can use one, if not both, of these authentication standards.
Key questions
Q: How should security teams implement passwordless authentication without creating new recovery risk?
A: Security teams should remove passwords from both primary login and recovery paths, then require stronger proofing for reset workflows than for normal sign-in.
Q: Why do WebAuthn and FIDO2 matter differently in an IAM programme?
A: WebAuthn is the application-facing API for browser-based passwordless authentication, while FIDO2 includes WebAuthn plus CTAP for the broader exchange with authenticators.
A: Organisations should prioritise passwordless authentication when password resets, complexity rules, and repeated logins are creating visible user frustration and recurring security exceptions.
Practitioner guidance
- Define the passwordless control boundary Document whether your programme is adopting WebAuthn alone or the full FIDO2 stack, and map each choice to the browsers, devices, and authenticators it must support.
- Inventory authenticators as identity assets Track enrolled security keys, platform authenticators, and mobile devices with the same governance discipline used for other human identity credentials.
- Design recovery before rollout Specify how users re-register, replace, or retire authenticators when devices are lost, changed, or unsupported, because passwordless failures usually show up in recovery flows.
Bottom line: Passwordless authentication changes human IAM governance by shifting the control problem from password strength to authenticator lifecycle and session assurance.

Passwordless authentication is a human IAM governance shift, not a point product decision. The article frames WebAuthn and FIDO2 as parts of a broader move away from passwords, but the operational change is in identity assurance, recovery, and device binding. That means the relevant question is not which protocol sounds stronger, but whether the organisation can govern enrolment, authentication, and lifecycle events consistently across the user base. The practitioner conclusion is simple: passwordless adoption changes the control model for human identity.
Passwordless adoption will keep moving from pilot to programme status, but the control conversation has to move with it. Human IAM teams should expect more pressure to prove that recovery, device binding, and session governance are working as one control surface rather than as separate features.
A question worth separating out:
Q: What does passwordless change about session governance?
A: It does not remove session risk. Once the user is authenticated, teams still need rules for session duration, reauthentication, and device changes, because passwordless only replaces the login secret, not the need to govern the active session.
