How should organisations govern multiple credential types in one identity programme?

Why This Matters for Security Teams

A single identity programme breaks down when certificate management, badge issuance, API keys, and authenticators are treated as separate problems. Security teams then lose a consistent view of who or what is entitled, when that entitlement expires, and how it is revoked. NHI Management Group’s research on the 2024 Non-Human Identity Security Report shows 88.5% of organisations say their non-human IAM practices lag behind or merely match their human IAM efforts, which is a warning sign for fragmented governance.

The practical risk is not just poor hygiene. Different credential types often have different owners, different renewal cadences, and different recovery paths, so access survives longer than intended after staff changes, service decommissioning, or incident response. That creates inconsistent offboarding and makes audit evidence hard to trust. The NIST Cybersecurity Framework 2.0 is explicit that governance and access control need repeatable processes, not ad hoc tool-specific exceptions. In practice, many security teams discover credential sprawl only after a stale certificate, badge, or API key has already been used to regain access.

How It Works in Practice

The most reliable model is to govern every credential type through the same lifecycle policy, even if the issuance technology differs. That means one ownership model for request, approval, issuance, renewal, rotation, revocation, recovery, and logging. The controls should be defined once and applied consistently to human identities, service accounts, workload identities, and physical access mechanisms where applicable.

In mature programmes, the lifecycle is usually managed through a central policy layer that routes to the right issuance system. For example, a certificate authority, IAM platform, badge system, and secrets manager can each handle their own mechanics while still answering to the same governance rules. This aligns with the NIST SP 800-63 Digital Identity Guidelines principle that identity assurance depends on consistent proofing and authenticator management, even when implementations vary.

• Assign one accountable owner per credential class and one policy owner for the overall programme.
• Standardise naming, inventory, and expiry metadata so audit can compare like with like.
• Use risk-based renewal and rotation windows rather than letting each system define its own defaults.
• Trigger revocation from the same offboarding event, whether the asset is a badge, certificate, token, or secret.
• Require recovery workflows to follow the same approval and evidence path as initial issuance.

For non-human and workload credentials, this model should also reflect what NHI Management Group calls out in the Ultimate Guide to NHIs: the highest-value controls are often the ones that make credential lifecycles visible across teams that normally operate in silos. Where secrets are involved, dynamic or short-lived material is usually safer than long-lived static credentials, as explored in the Ultimate Guide to NHIs — Static vs Dynamic Secrets.

These controls tend to break down when organisations inherit multiple legacy systems with incompatible audit fields and no shared owner for revocation.

Common Variations and Edge Cases

Tighter lifecycle control often increases administrative overhead, requiring organisations to balance governance consistency against system-specific constraints. That tradeoff is real in environments where physical badges, certificates, and software tokens sit under different operational teams or even different regulatory scopes. Current guidance suggests the right answer is not to force every credential into the same tooling, but to force them into the same policy and evidence model.

Edge cases show up when credentials have different expiry logic. A badge may need human revalidation, a certificate may rotate automatically, and an API key may be tied to deployment events. The programme should still record the same core facts: who owns it, what it grants, when it expires, how it is revoked, and what evidence proves the action happened. That is also where the OWASP Non-Human Identity Top 10 is useful, because it highlights secret handling, overprivilege, and lifecycle weaknesses that often cross credential categories.

A useful operational rule is to make exceptions explicit and time-bound. If a legacy badge system cannot support immediate revocation, document the compensating control, the expiry date for the exception, and the owner responsible for replacement. The Top 10 NHI Issues research is a reminder that secret sprawl and inconsistent governance are usually symptoms of the same structural problem. There is no universal standard for one platform that governs every credential type perfectly, so the best practice is evolving toward common lifecycle policy with federated enforcement.
