TL;DR: AI agent identity is clearest when token format, workload proof, delegation chain and service onboarding are separated, according to raxIT Labs. That layered proof still leaves authorization unresolved, so governance has to track what the agent may do, not only who it is.
Editorial analysis by NHI Mgmt Group, based on content published by raxIT Labs: “Four Layers of AI Agent Identity: The Model I Use”.
Key questions
Q: Why is proving an AI agent’s identity not enough to approve its actions?
A: Because identity proof answers who is acting, not whether the action is justified.
Q: What breaks when AI assistants borrow human sessions or tokens?
A: What breaks is attribution.
Q: How should security teams govern AI systems that can act without human approval?
A: Security teams should govern autonomous AI the same way they govern other high-risk identities, but with runtime enforcement instead of periodic review.
Practitioner guidance
- Define the agent as a distinct actor in every workflow Keep the human subject, the agent actor and any downstream sub-agent separate in logs, policy and incident review so delegated work remains attributable.
- Require workload attestation before issuing agent credentials Use attested workload identity as the gate for agent authentication so short-lived credentials are issued only to the expected runtime environment.
- Replace borrowed-user-token shortcuts with actor-chain delegation Preserve the full chain of who authorised the action and which agents handled it, rather than collapsing everything into the end user’s identity.
Bottom line: AI agent identity is best understood as layered proof, but proof of identity still does not equal approval of action.

Identity proof and authorization are no longer the same control problem: The article’s central insight is that a complete agent identity stack can still leave the wrong action untouched. That is a structural governance issue, not a missing feature. Once the token, workload and delegation chain are sound, the remaining question is behavioral legitimacy, which sits outside identity proof alone. Practitioners should stop treating identity completion as proof of safe action.
A question worth separating out:
Q: Why do AI agents need separate governance for workload identity and delegated user access?
A: Because the agent is not the user, and the user is not the process. Workload identity proves which runtime is acting, while delegated credentials represent whose authority it is using. If those are merged, revocation, auditing, and scope control become ambiguous, especially when the agent calls external services on the user's behalf.
