Passwordless programmes still need access reviews because the organisation is managing factors, devices, and recovery channels, not just passwords. Reviews should confirm that enrolled factors are current, that unused devices are revoked, and that fallback methods remain appropriate for the user’s role and risk level.
Why This Matters for Security Teams
Passwordless reduces password theft, phishing, and reset abuse, but it does not remove identity governance. Security teams still have to review enrolled factors, device bindings, recovery methods, and the people who can approve fallback access. If those controls drift, a passwordless rollout can leave old phones, stale authenticators, and weak recovery paths sitting behind a cleaner login experience.
This is the same governance problem NHI Mgmt Group highlights in the Ultimate Guide to NHIs: identities are secure only when the full lifecycle is visible, not just the sign-in method. The underlying lesson aligns with the OWASP Non-Human Identity Top 10 in a broader sense, because access hygiene fails when organisations trust enrolment state more than ongoing use and ownership.
Reviews matter because passwordless programmes often accumulate hidden privilege through recovery channels, shared devices, and unused authenticators that were never removed after role changes. In practice, many security teams encounter this only after a lost device, a compromised help desk workflow, or an offboarding miss has already created a reusable access path.
How It Works in Practice
Passwordless access reviews should examine the identity binding around the factor, not just the factor itself. For example, a passkey, authenticator app, smart card, or device certificate may all be valid, but each one still needs an owner, a current purpose, and a revocation path. Reviewers should confirm that the enrolled device is still issued to the right person, the factor matches the user’s current role, and any recovery options are still appropriate for the account’s sensitivity.
Current guidance suggests treating this as a periodic attestation exercise plus event-driven cleanup. That means reviewing:
- which devices are enrolled and whether they are still managed, compliant, and in active use
- which recovery channels exist, including help desk reset paths and backup codes
- whether step-up access is required for privileged roles or high-risk systems
- whether inactive factors should be revoked automatically after transfer, leave, or termination
Implementations are stronger when the review process is tied to authoritative sources such as HR status, device management, and privileged access workflows. NHI Mgmt Group’s NHI Lifecycle Management Guide reinforces the same principle: identity state should change when business state changes, not only during annual audits. Teams can also anchor operational controls to the Ultimate Guide to NHIs — Key Challenges and Risks because stale access paths are often the real failure mode, not the primary login method.
Where this guidance breaks down is in highly distributed environments with unmanaged endpoints, contractor-heavy populations, or shared-device workflows, because ownership and factor freshness become harder to verify at scale.
Common Variations and Edge Cases
Tighter passwordless review cycles often increase administrative overhead, so organisations have to balance stronger assurance against user friction and support cost. That tradeoff is especially visible when the programme includes BYOD, field workers, emergency access, or shared kiosk devices.
Best practice is evolving for passkey-heavy deployments. Some teams review only enrolled factors; others also review recovery questions, phone-based fallback, and account recovery approvers. There is no universal standard for this yet, but the safer approach is to treat every bypass mechanism as part of the access surface. If a help desk can reset a passwordless account without strong verification, that path deserves the same scrutiny as any privileged credential.
This is also where false confidence appears. Passwordless can reduce one category of compromise while leaving another untouched, especially when the account still has broad application access or privileged entitlements. NHI Mgmt Group’s 52 NHI Breaches Analysis and the OWASP guidance both point to the same operational lesson: the control that looks modern is not always the control that limits blast radius. Reviews remain necessary because the real question is not whether a password exists, but whether every active path into the account is still justified.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0 and NIST SP 800-63 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Reviews should verify factor ownership, lifecycle, and revocation. |
| NIST CSF 2.0 | PR.AC-1 | Access reviews support ongoing access control validation. |
| NIST SP 800-63 | IAL/AAL/FAL | Assurance depends on current authenticators and recovery channels. |
Revalidate authenticator strength and recovery bindings whenever risk or role changes.
