How should IAM and PAM teams decide whether password elimination is complete?

Why This Matters for Security Teams

Password elimination is not complete when a legacy login screen disappears. It is complete only when passwords are no longer required anywhere an identity can authenticate, recover, escalate, or be administered. That includes desktops, remote access, break-glass paths, shared admin accounts, and privileged workflows that still depend on a fallback secret. NIST SP 800-53 Rev. 5 Security and Privacy Controls frames this as a control design issue, not just a user experience issue: if the control plane still relies on secrets, the risk remains. NHIMG research shows why this matters. In the Ultimate Guide to NHIs, 97% of NHIs carry excessive privileges and 71% are not rotated in recommended time frames, which is the same pattern that appears when “passwordless” programs leave exceptions in place. In practice, many security teams discover the last password only after a recovery event or privilege audit exposes it, rather than through intentional decommissioning.

How It Works in Practice

Teams should test password elimination by tracing every identity path end to end, not by counting which user populations have moved to phishing-resistant authentication. Start with interactive user access, then validate remote access, device unlock, privileged elevation, service administration, and operational recovery. A passwordless programme is only credible when each path has a non-secret alternative and the fallback is not quietly reintroducing shared credentials.

For IAM and PAM, the operational question is whether the organisation still depends on a reusable secret to prove identity, approve elevation, or regain access after lockout. Current guidance suggests mapping those paths against controls such as device-bound authentication, federation, just-in-time elevation, and vaultless recovery flows. NIST SP 800-53 Rev. 5 Security and Privacy Controls can help teams document where alternate authenticators, account recovery, and privileged access workflows still require a password. For privileged identities, the Azure Key Vault privilege escalation exposure example shows how a single mis-scoped privileged path can reintroduce secret dependence even after the front door looks modern.

• Check whether all human login flows use phishing-resistant methods and no fallback password.
• Verify PAM elevation does not depend on shared credentials, shared local admin passwords, or emergency secrets.
• Review operational recovery flows, including help desk resets, device replacement, and break-glass access.
• Confirm service accounts, API keys, and automation paths are separately governed so they do not become the hidden exception.

Teams should also validate that “passwordless” for end users has not simply shifted risk into privileged shared access, as seen in incidents such as the BeyondTrust API key breach. These controls tend to break down when remote support, legacy applications, or emergency recovery still require a secret because those environments are rarely fully redesigned at the same pace as the primary login journey.

Common Variations and Edge Cases

Tighter password elimination often increases recovery friction, so organisations have to balance stronger assurance against operational continuity. The hardest edge cases are not everyday logins but the systems designed to “save” access when everything else fails.

Legacy applications, contractors, offline endpoints, and shared service desks often force teams into exceptions. Best practice is evolving, but there is no universal standard for this yet: some programmes allow a bounded break-glass password with strict monitoring, while others require a separate recovery authority and hardware-backed authentication. The key is that exceptions must be explicitly temporary, logged, and reviewed. If a password remains because a vendor console, mainframe, or field device cannot yet support modern authenticators, that is a migration gap, not completion. NHIMG’s Code Formatting Tools Credential Leaks research is a reminder that secrets often persist in overlooked tooling rather than official IAM paths. The same is true for “passwordless” programmes: completion is measured by the removal of all practical secret dependency, not by the number of modern login methods deployed.
