Agentic AI identity taxonomy: what IAM teams need to separate

TL;DR: AI agents need different identity controls depending on how they interact with systems, where they run, and whose authority they inherit, with browser-based and programmatic use cases requiring different credential handling, according to 1Password. The central issue is that agentic access breaks assumptions built for either users or workloads, so governance must distinguish each agent’s operating model.

Editorial analysis by NHI Mgmt Group, based on content published by 1Password: “An Identity Security taxonomy for Agentic AI”.

Key questions

Q: How should teams separate browser-based agents from programmatic agents in IAM?

A: They should treat the interaction path as a control boundary.

Q: Why does agent runtime location matter for identity controls?

A: Because an endpoint agent and a remote cloud agent inherit different trust conditions.

Q: When should organisations distinguish employee, internal and customer agent authority?

A: Always when the same agent can act on behalf of different principals.

Practitioner guidance

  • Define separate control paths for browser and programmatic agents Map each agent to its actual interaction channel, then assign credential type, authorization logic and logging based on that channel rather than on the fact that it is an AI system.
  • Classify the runtime boundary before issuing access Document whether each agent runs on an endpoint or in remote cloud infrastructure, because that choice determines which trust assumptions, monitoring tools and secret-handling methods are valid.
  • Record whose authority the agent is using Tag each deployment as employee, internal company or external customer context so vault ownership, approval flows and audit records stay aligned to the principal behind the action.

Bottom line: Agentic AI identity cannot be governed as one generic class because browser, programmatic and remote agents follow different access and trust patterns.

Agentic AI taxonomy is becoming a governance control, not a naming exercise. The article's three-way split across interaction mode, runtime location and delegated authority is useful because identity teams cannot secure agentic systems with a single policy tier. Browser access, remote execution and authority inheritance each produce different control demands. The implication is that agentic identity programmes need classification before they need scale.

A few things that frame the scale:

A question worth separating out:

Q: What should organisations do when AI agents start using inherited credentials?

A: Treat those agents as governed identities rather than untracked automation. Scope their credentials tightly, log every action back to a human owner, and make revocation part of the operational model. Otherwise, agent activity will outgrow session-based IAM assumptions and create access that is hard to explain or remove.
