Authorization vs Authentication in Agentic Financial Systems

Knowing who an agent is and knowing what it is permitted to do are separate problems. Most enterprises have solved the first. Few have addressed the second — and in agentic financial workflows, that gap is where risk lives.

Authentication answers "who"

API keys, OAuth tokens, and service credentials answer a narrow question: is this request coming from a system we recognize? That's necessary, but it says nothing about what the agent behind that credential should be allowed to do in this specific instance.

Authorization answers "what"

Authorization is contextual and dynamic — it depends on transaction amount, counterparty, timing, and the delegation chain that granted the agent its authority in the first place. It can't be reduced to a static credential.

1. Identity is established (authentication)
2. Delegation is resolved — who granted this agent its authority, and under what policy
3. The requested action is checked against that policy's actual scope
4. The decision — and the evidence behind it — is recorded before execution

Why most enterprises stop at authentication

Authentication is a solved problem with mature tooling. Authorization for autonomous agents is not — most treasury and ERP platforms were never designed to evaluate policy in real time against an agent's intent, only a human's login.
