TL;DR: Unosecur finds that AI agent credentials are often created faster than teams can track, store, rotate, or revoke them, leaving hundreds of API keys and tokens without clear ownership. The lifecycle assumption that access lasts long enough for periodic review collapses when agents operate at machine speed.
Editorial analysis by NHI Mgmt Group, based on content published by Unosecur: “AI agent credential lifecycle: issuance, storage, rotation and revocation”.
Key questions
Q: What breaks when AI access is managed on the same cadence as human access reviews?
A: Periodic access reviews miss the short-lived but high-impact privilege growth that can happen between reviews.
Q: When do short-lived credentials become insufficient for AI agent risk?
A: Short-lived credentials become insufficient when an organisation cannot see, scope, and revoke every grant the agent touches.
Q: What are the signs that AI agent credential governance is breaking down?
A: Common warning signs include credentials scattered across unrelated vault items, weak naming that makes agent access hard to search, and no clear separation between human and agent workflows.
Practitioner guidance
- Define every agent credential at issuance Tie each credential to one agent identity, a specific scope, and an expiry so access does not outlive the task that required it.
- Move credentials out of code and images Store all agent credentials in a governed secrets store or vault and require runtime retrieval instead of embedding secrets in repositories, workflow files, or container artefacts.
- Replace scheduled rotation with expiry or events Use short-lived credentials by default and trigger rotation on role changes, suspicious access, or deprecated tools rather than waiting for a calendar cycle.
Bottom line: AI agent credential governance fails when issuance, storage, rotation, and revocation are treated as separate workflows instead of one lifecycle.

Unosecur's full article covers the operational detail this post intentionally leaves for the source:
- A stage-by-stage walkthrough of issuance, storage, rotation, and revocation for AI agent credentials
- Guidance on when short-lived credentials should replace scheduled rotation in agent environments
- Examples of storage failures such as hardcoded values, plaintext workflow secrets, and embedded deployment artefacts
- Practical considerations for revocation, including cached sessions and downstream tokens that still remain active

Continuous credential governance is the correct control model for AI agents. The article shows that issuance, storage, rotation, and revocation cannot be treated as isolated tasks when the identity is an agent. A lifecycle that depends on separate team handoffs will always lose visibility between systems, because the credential can outpace the process that is meant to govern it. The implication is that AI agent credential governance must be designed as one recordable lifecycle, not four disconnected checklists.
A few things that frame the scale:
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them, according to the Ultimate Guide to NHIs.
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Who should own governance for AI agent credential custody?
A: Ownership should sit with IAM, PAM, and platform security together, because the issue spans identity lifecycle, privileged credential handling, and workload execution. Teams should govern where the token lives, how it is bound to the process, and whether the runtime can replay it outside the intended request path.
