TL;DR: Enterprises struggle to govern service accounts, API keys, OAuth tokens, and AI agents because identity programs were built for people, leaving critical automation exposed through missing ownership, weak lifecycle controls, and blind spots in review, according to Omada Identity. The governance case is no longer about inventory alone; it is about proving accountability, lifecycle control, and auditability before autonomous agents scale further.
At a glance
What this is: This is a governance analysis of why non-human identities and AI agents fall through people-designed identity programs, with five missing controls identified as the core failure pattern.
Why it matters: IAM, IGA, and PAM teams need this because NHI governance now has to prove ownership, reviewability, and lifecycle control before AI agents inherit the same gaps.
Context
Non-human identities are credentials and identity records used by systems rather than people, including service accounts, API keys, OAuth tokens, and the identities that AI agents rely on to act. The governance gap appears when these identities exist outside the ownership, review, and lifecycle controls that identity programmes were originally built for.
This article argues that the problem is not just shadow inventory. It is a programme design issue: if an identity can authenticate, access production, and remain active without a named owner or review trail, then the control model is still human-centric even when the workload is machine-driven.
For organisations building AI agent governance, that matters because the same governance foundation used for NHIs becomes the minimum evidence base for autonomous access decisions. The article’s central claim is that AI agent oversight starts with NHI discipline, not with a separate governance stack.
Key questions
Q: What breaks when non-human identity ownership is unclear?
A: When ownership is unclear, rotation stalls, reviews default to approval, and nobody feels safe removing access. That creates orphaned identities, stale credentials, and broad permissions that persist because the organisation cannot prove what depends on them. The result is a growing attack surface with no accountable decision-maker.
Q: Why do long-lived NHI credentials increase supply-chain risk?
A: They increase supply-chain risk because build systems, package installs, and developer tools can harvest and reuse them without a separate exploit chain. A long-lived credential stays useful long after the initial exposure, which means one compromise can extend into cloud, CI/CD, and secrets infrastructure.
Q: How should teams certify non-human identity access without breaking production?
A: Teams should certify non-human access with workload evidence, not permission lists. Build a chain from consumer to credential to identity to resource, then use observed activity, access surface, and credential posture to decide whether to approve, right-size, rotate, reassign, or disable. That keeps reviews defensible while reducing outage risk.
Q: How can organisations govern AI agents that use service accounts and tokens?
A: Treat those credentials as governed non-human identities with lifecycle controls, not as temporary developer conveniences. That means provisioning them with clear scope, monitoring how they are used, rotating them on a schedule, and removing them when the workflow ends. The goal is to keep the agent’s privilege bounded across its entire operating life.
Technical breakdown
Why people-first identity governance fails for NHIs
Traditional identity governance assumes a human owner, a stable role, and a lifecycle that follows HR events. Non-human identities do not behave that way. They are often created by engineers, embedded in pipelines, and left behind when projects end or systems change. Because they authenticate and operate independently of a person’s work pattern, they need governance records that track purpose, scope, credential age, and accountable ownership. Without that context, inventory is only a list, not a control surface.
Practical implication: build NHI records around purpose, scope, and ownership, not just discovery.
How lifecycle governance works differently for service accounts and AI agents
Lifecycle governance for NHIs cannot depend on HR triggers. A service account or token may need review when an application is retired, a project closes, or a scope changes, not when someone changes jobs. The article extends the same logic to AI agents, but with a key difference: an agent’s behaviour can change with context even when its identity record looks stable. That means lifecycle governance has to cover provisioning, scope change, credential age, and offboarding as explicit governance events, not implicit side effects.
Practical implication: define NHI lifecycle triggers for creation, scope change, retirement, and rotation.
Why certification and risk signals must move into NHI review cycles
Access review campaigns usually ask whether a person still needs access. For NHIs, reviewers need to know whether the identity still has a valid purpose, whether its privilege matches that purpose, and whether it is actually being used. The article’s risk model is practical: missing owner, production access without justification, excessive access relative to usage, overdue rotation, dormant privileges, and unusual privilege combinations are all signals that governance has drifted. That changes certification from a checkbox into a control that proves ongoing accountability.
Practical implication: include purpose, usage, and rotation age in NHI certification evidence.
Threat narrative
Attacker objective: The attacker objective is to find a valid non-human credential that remains active long enough to access sensitive systems without triggering ownership, review, or lifecycle controls.
- The exposure begins when a non-human credential is created or copied into a workflow without central registration, so the organisation loses sight of where it exists and what it can access.
- Privilege is then preserved by missing ownership, no expiration, and no rotation requirement, which keeps the credential valid long after its original purpose should have ended.
- The impact is extended exposure of production access and sensitive systems, because the identity never enters a review cycle that could question, constrain, or revoke it.

NHI Mgmt Group analysis
People-first identity governance is structurally incomplete for non-human identities. The article is correct that service accounts, API keys, OAuth tokens, and AI agents do not fit the HR-driven assumptions behind many identity programmes. Inventory alone does not govern these identities because governance depends on ownership, lifecycle, and review context. The implication is that identity programmes must stop treating machine credentials as edge cases and start treating them as core governed identities.
Ownership is the governance primitive that inventory cannot replace. A discovered NHI with no named accountable person is not governed, even if it is catalogued. That is the control gap the article exposes most clearly: without an owner who can justify purpose, scope, and continued need, the identity is effectively unactionable. Practitioners should read this as a warning that accountability is the first real control boundary for NHI governance.
Long-lived credentials create governance debt that review cycles cannot repay. If an API key, token, or agent credential is allowed to persist indefinitely, the programme accumulates risk faster than certification can clear it. The article’s five-failure model shows that rotation, review, and escalation must be connected, otherwise detection has no enforcement path. Practitioners should treat credential age and renewal logic as governance evidence, not just operational hygiene.
AI agent governance inherits the NHI foundation but adds decision scope pressure. The article is explicit that agents rely on the same credential types as other NHIs, but their autonomy changes the governance question from static access to authorised behaviour. That means the NHI foundation is necessary but not sufficient for agents, because governance must also prove what the agent was allowed to do and whether its actions stayed within declared purpose. Practitioners should prepare for that shift now.
Governance by review alone is too slow for continuously created NHIs. The article’s emphasis on continuous discovery is the right direction because periodic snapshots lag behind real identity creation. A control model that only sees identities at review time will always be behind the estate it is meant to govern. The practitioner conclusion is simple: continuous inventory, or continuous blind spots.
From our research library:
- 19% of organisations give AI systems dramatically more access than human employees, nearly one in five granting unrestricted privilege, according to the 2026 Infrastructure Identity Survey.
- NHIs outnumber human identities by 25x to 50x in modern enterprises, according to the Ultimate Guide to NHIs.

What this signals
Continuous governance now matters more than periodic review: NHI programmes that only discover identities during scheduled reviews will keep missing the identities most likely to drift, expire, or be abandoned. The operational signal to watch is whether inventory, ownership, and rotation are updated as events happen, not after the fact.
The same governance pattern is now becoming the baseline for AI agents. If an organisation cannot prove who owns a service account, why it exists, and when it must be removed, it is not ready to govern an agent that can make context-sensitive decisions and then act through the same credential types.
Review evidence is only useful when it can be acted on. That means the programme needs a clean path from risk signal to owner, and from owner to revocation or renewal, otherwise certification becomes documentation of delay rather than control.
For practitioners
- Implement continuous NHI inventory Track service accounts, API keys, OAuth tokens, managed identities, and AI-agent credentials across cloud, CI/CD, and SaaS environments as a live estate, not a periodic export.
- Assign a named owner to every non-human identity Require a recorded accountable person for each NHI so every credential has a clear approver for purpose, access scope, and retirement decisions.
- Trigger lifecycle reviews on scope changes and project closure Use governance events such as application retirement, team reorganisation, or access scope change to prompt review and removal of unneeded NHIs.
- Fold NHI purpose and usage into certification Ask reviewers to confirm why the identity exists, what it accessed, when it was last used, and whether its current privilege still matches declared purpose.
- Escalate overdue credential age as a governance event Set thresholds for token and key age, then route overdue rotation items to the named owner with a recorded decision trail and revocation path.
Key takeaways
- The article shows that NHI governance fails when identities are discovered but not owned, reviewed, or retired through a defined lifecycle.
- Its five-failure model ties weak inventory, missing ownership, absent lifecycle control, skipped certification, and poor escalation to persistent exposure.
- The practical lesson is to move governance from periodic review to continuous accountability before AI agents inherit the same blind spots.

Key terms
- Non-Human Identity (NHI): A digital identity assigned to a non-human entity such as a software application, service account, API key, bot, machine, or AI agent that enables it to authenticate and interact with systems without direct human involvement. NHIs now outnumber human identities in most enterprises by 25 to 50 times.
- NHI Ownership Transfer: NHI ownership transfer is the reassignment of a non-human identity from one employee to another during a change event such as offboarding. It is used when the credential still supports a live business process and cannot simply be revoked. Effective transfer requires context, dependency mapping, and governance approval.
- NHI Compliance: NHI compliance is the practice of proving that machine identities are discovered, owned, controlled and monitored in line with policy and regulation. It turns lifecycle governance into evidence that can survive audit, incident review and change over time.
- Credential Lifecycle: Credential lifecycle is the process of issuing, rotating, expiring, and revoking secrets, certificates, and tokens across their usable life. For non-human identities, lifecycle discipline is the core control that separates temporary access from persistent exposure.
