TL;DR: As cloud-native automation and AI expand machine identities, service accounts, tokens, and API keys are multiplying faster than human-centric IAM can govern them, leaving over-permissioned access paths and persistent credential risk, according to Token Security. Least privilege becomes operational only when discovery, lifecycle control, and short-lived access are enforced together.
Editorial analysis by NHI Mgmt Group, based on content published by Token Security: “Operationalizing Least Privilege for Non-Human Identities”.
By the numbers:
- NHIs outnumber human identities by 25x to 50x in modern enterprises, according to the Ultimate Guide to NHIs.
Key questions
Q: What breaks when non-human identities are governed like human users?
A: Lifecycle triggers, ownership, and review processes stop working because machine identities do not generate joiner, mover, or leaver events.
Q: What problem does ownership attribution solve for service accounts and API keys?
A: It closes the gap between exposure detection and accountable remediation.
Q: How do security teams know whether least privilege is actually working?
A: Least privilege is working when identities have narrowly scoped permissions, unused credentials are removed or quarantined, and repeated access reviews consistently shrink entitlements.
Practitioner guidance
- Inventory every non-human identity Build a centralized inventory of service accounts, API keys, OAuth tokens, SSH keys, certificates, cloud roles, and workload identities across cloud, SaaS, and on-prem environments.
- Map identity-to-resource access Document what each non-human identity can reach, which actions it can perform, and whether those permissions are actually used in production.
- Replace broad roles with task-scoped access Scope permissions to the specific resource and action set needed for the workload, then remove unused privileges as usage patterns change.
Bottom line: Non-human identity sprawl creates a wider attack surface than human-centric IAM models are built to manage.

Operational least privilege for non-human identities is really lifecycle governance in disguise: access scope only becomes meaningful when the identity is owned, inventoried, reviewed, rotated, and retired as a single control chain. The article correctly shows that service accounts and tokens fail when those steps are fragmented. Practitioners should treat lifecycle ownership as the control plane for machine access.
A few things that frame the scale:
- 92% of cloud identities are over-permissioned and 62% are dormant.
A question worth separating out:
Q: What should teams do when a non-human identity no longer needs access?
A: Revoke or decommission it through a lifecycle process, not as an ad hoc cleanup task. The identity should be retired, its credentials invalidated, and its ownership closed out so access does not outlive the service or integration it supported.
