TL;DR: Agentic commerce cannot safely start with the agent because trust depends on a verified human, an authenticated device, and a cryptographic binding that defines scope, according to Prove Identity. The governance shift is that identity controls must extend from the person at login to the agent acting on their behalf, or delegation becomes unauditable and overbroad.
Editorial analysis by NHI Mgmt Group, based on content published by Prove Identity: “The Crisis of Identity, Part 2: From Human Identity to Agent Authority with the Prove Identity Graph”.
Key questions
Q: How should IAM teams govern agent authority when it is delegated from a human user?
A: Start with the verified human, the authenticated device, and the explicit scope the agent is allowed to inherit.
Q: Why do human login controls become insufficient once agents act on behalf of users?
A: Login proves a person authenticated at a point in time, but it does not prove that every downstream agent action still reflects valid delegated authority.
Q: What breaks when delegated agent authority is not tied to an authenticated device?
A: The trust chain loses its anchor.
Practitioner guidance
- Define the delegation boundary Map where human identity ends and agent authority begins.
- Bind agent authority to device trust Require authenticated devices as part of the trust decision for delegated action.
- Use real-time validation for inherited trust Re-evaluate delegated authority when the identity signal changes, rather than relying on a one-time approval.
Bottom line: The article's central point is that agent authority depends on a verified human and an authenticated device, not on the agent acting alone.

Agent authority is not a new identity primitive, it is delegated identity governance. The article correctly reframes AI agents as actors that inherit trust from a verified human and an authenticated device. That means the control question is not whether the agent is powerful enough to operate, but whether the delegation chain is explicit, bounded, and still valid at the moment of action. Practitioners should treat this as a governance extension of human IAM, not a separate trust exception.
A few things that frame the scale:
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job, according to the 2026 Infrastructure Identity Survey.
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems. Organisations failing to scope AI access properly are 4.5x more likely to experience a security incident, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: What should security teams do when the trust conditions behind an agent change?
A: Reassess the agent's authority immediately against the verified human, the device state, and the conditions that originally justified delegation. If any of those inputs shift, the safer assumption is that the agent's scope should narrow, expire, or require fresh authorisation before continuing.
