They should be treated as lifecycle objects, not static artefacts. When a person changes role or leaves, the organisation must re-issue, downgrade, or revoke the relevant credentials and ensure the change reaches every verifier that trusts them. If not, distributed identity simply extends the life of outdated trust.
Why This Matters for Security Teams
Joiner mover leaver processes were designed for human employment events, but distributed identities do not behave like a single badge or directory record. A service account, API key, certificate, or workload token can be trusted by multiple verifiers across apps, clouds, and pipelines, so a role change must trigger re-issuance, privilege reduction, and revocation everywhere. That is why lifecycle governance is not optional. NHI Mgmt Group notes that only 20% of organisations have formal offboarding and revocation processes for API keys, while 91.6% of secrets remain valid five days after notification in breach scenarios, based on the Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs.
Security teams often miss that distributed identity expands the blast radius of a JML failure because trust is replicated, not centralised. A single stale credential can keep access alive long after HR and IAM have updated the human record. That is also why lifecycle events need to be treated as security triggers, not administrative cleanup, and why the control plane must reach every relying party. In practice, many security teams encounter privilege persistence only after a former employee or moved contractor has already retained access through an overlooked token, rather than through intentional offboarding.
How It Works in Practice
The practical model is to map each joiner mover leaver event to the identities and credentials it actually affects. For humans, that may mean updating role assignments. For distributed identities, it usually means a broader set of actions: rotate secrets, shorten token lifetimes, rebind workload identities, and invalidate certificates or API keys that were issued for the previous role. Current guidance from NIST Cybersecurity Framework 2.0 supports lifecycle-aware access governance, but there is no universal standard for how every distributed identity type should be sequenced.
- On joiner, issue the minimum set of credentials needed for the new function, with explicit owners and expiry dates.
- On mover, re-evaluate every trust relationship, not just the directory role, because distributed identities may be embedded in CI/CD, SaaS integrations, and automation tools.
- On leaver, revoke upstream credentials and downstream trust artifacts, then confirm that each verifier has actually stopped accepting them.
- Where possible, prefer short-lived tokens and centrally managed workload identity over long-lived static secrets.
This is where distributed identity and JML can fail if the organisation relies on a single identity source of truth but does not propagate changes into all consuming systems. The JetBrains GitHub plugin token exposure is a useful reminder that one exposed credential can continue to authenticate until it is discovered and revoked, regardless of the original user state. Lifecycle controls tend to break down when credentials are embedded in code, cached in automation, or replicated into third-party tools because the revocation event does not reach every verifier in time.
Common Variations and Edge Cases
Tighter lifecycle control often increases operational overhead, requiring organisations to balance faster revocation against developer friction and service reliability. The hardest cases are delegated access, cross-tenant service connections, and machine-to-machine integrations where the “owner” of the credential is not the person whose employment status changed. Best practice is evolving here, especially for shared service identities and brokered token exchange models.
One common edge case is when a mover event should not fully revoke an identity because the underlying workload still needs to function. In that case, the right response is usually downgrade plus re-issue, not blanket deletion. Another is contractors who are not in HR systems at all, which means JML must pull from vendor management, IAM, and platform telemetry together. The control objective is the same: ensure the old trust path is dead, not merely marked inactive in one system.
For broader lifecycle guidance, the Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs is the most relevant NHIMG reference, and NIST CSF 2.0 remains the clearest external baseline for access governance. Organisations that rely on periodic access reviews alone usually miss distributed identities that were copied, delegated, or re-issued outside the main directory workflow.

OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0 and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-03 | Covers secret rotation and revocation, which are central to JML for distributed identities. |
| NIST CSF 2.0 | PR.AC-1 | Access provisioning and deprovisioning map directly to lifecycle changes for distributed identities. |
| NIST AI RMF | Lifecycle governance supports accountable, controlled AI and automated identity behaviour. |
