Both, but the governance part is usually the one that fails first. Passkeys improve the login factor, yet the real risk sits in identity proofing, linking policy, and account lifecycle handling, especially when federated providers share or replace credentials.
Why passkeys change login but not the identity problem
Passkeys are an authentication upgrade, but they do not remove the need to know who is entitled to sign in, how that entitlement is proven, and what happens when the account changes hands. In practice, the security win comes from stronger authenticators, while the failure modes often shift to enrollment, recovery, federation, and account ownership decisions.
That is why a passkey rollout should be assessed as more than a sign-in project. If you only measure phishing resistance or help desk deflection, you can miss whether the organisation has sound proofing, recovery, and linking rules for the account that the passkey protects.
Where identity governance becomes the deciding factor
The governance question starts before the passkey exists and continues after it is issued. Organisations need to define which identity is being bound to the credential, which source of truth authorises that binding, and how step-up or reproofing works when a user changes device, employer, role, or federated login path.
That is why passkey rollout is closely tied to identity lifecycle and identity governance fundamentals, especially where multiple directories, HR feeds, or federated providers can create competing account records. The control problem is not only “can the user authenticate”, but “is the right account still attached to the right person under the right policy”.
Federated environments make this sharper. If a provider issues, shares, or replaces credentials, the organisation must still own the rules for provisioning, deprovisioning, recovery, and recertification. Passkeys can simplify the login experience, but they do not automatically solve joiner-mover-leaver discipline or account lifecycle cleanup.
What failure looks like in real deployments
The most common failure pattern is treating passkeys as a replacement for governance rather than as a stronger authenticator inside a governed identity process. That creates gaps when help desk recovery becomes the new attack surface, when old passwords remain active, or when one account can be silently rebound to a different device or identity source without review.
This is also where governance and authentication intersect with role design, offboarding, and access review. A well-run rollout should be able to explain who can enroll a passkey, who can reset it, what evidence supports recovery, and what triggers re-verification after high-risk events such as device loss or account takeover suspicion. For organisations building that control set, the passkeys rollout guidance is most useful when read alongside lifecycle and recovery controls, not as a standalone authentication recipe.
Risk and Threat Considerations
Passkeys reduce phishing exposure, but they can also mask governance weaknesses if teams assume the new factor makes identity proofing, account recovery, and federation policy less important. The risk is highest where recovery paths are weak, federated assertions are over-trusted, or device binding and account ownership are not revalidated after change events.
Failure mechanism: An attacker, insider, or confused recovery process can exploit weak proofing, stale entitlements, or loose federation links to attach a valid passkey to the wrong account, preserve access after offboarding, or redirect recovery to an unauthorised device.
Impact: The organisation gets a stronger login factor on paper but still loses account integrity, so compromise can persist through trusted recovery channels, missed deprovisioning, or silent privilege carryover.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-63, NIST SP 800-53 Rev 5 and OWASP ASVS set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-63 | Digital Identity Guidelines | Passkeys and recovery map directly to authenticator assurance and proofing guidance. |
| Recommendation — Align enrollment and recovery to phishing-resistant authenticator and proofing guidance. | ||
| NIST SP 800-53 Rev 5 | IA-5 — Authenticator Management | Passkey rollout depends on lifecycle control of authenticators, resets, and revocation. |
| IA-2 — Identification and Authentication (Organizational Users) | Passkeys change how users authenticate to enterprise accounts and federated sessions. | |
| AC-2 — Account Management | Enrollment, linking, recovery, and offboarding make passkeys an account governance issue too. | |
| Recommendation — Manage passkey issuance, rotation, and revocation under authenticator lifecycle controls. Use strong user authentication requirements for passkey-enabled access paths. Tie passkey binding and removal to authoritative account lifecycle events. | ||
| ISO/IEC 27001:2022 | A.5.16 — Identity management | Passkey rollout requires governed identity binding and ownership across account records. |
| A.5.17 — Authentication information | Passkeys are authentication material whose issuance and recovery must be controlled. | |
| A.5.18 — Access rights | Passkey rollout must preserve review and removal of access when accounts change or end. | |
| Recommendation — Maintain clear identity ownership and binding rules for passkey enrollment and recovery. Protect passkey-related authentication material through controlled issuance and recovery. Review and revoke access rights independently of the authentication method. | ||
| OWASP ASVS | V10 — OAuth and OIDC | Federated login paths often determine how passkeys are issued, trusted, and recovered. |
| V6 — Authentication | Passkeys are an authentication mechanism that must meet strong enrollment and recovery requirements. | |
| Recommendation — Verify federated sign-in and account binding rules for passkey-enabled flows. Validate authenticator enrollment, reset, and recovery paths for passkey deployments. | ||
Practitioner Guidance
What to prioritise: Treat rollout design as an account governance change first, then an authenticator change. The first control questions should be who can bind a passkey, what proof is required, how recovery is governed, and how revocation works when employment or device status changes.
What to verify: Confirm that passkey enrollment, reset, and recovery are tied to the organisation’s authoritative identity record, not just to whichever login provider is easiest to use. If those paths cannot be audited or challenged, the rollout is incomplete even if the authenticator itself is phishing resistant.
Common mistake: Teams often modernise sign-in while leaving legacy credentials, weak help desk verification, and broad federation trust in place. That creates a better front door with the side gate still open.
Practitioner takeaway: If passkeys are deployed without lifecycle and ownership controls, the organisation has upgraded authentication but not identity governance, and the latter is usually where the real exposure remains.
