AI Agent Identity Machine & Agent Identity # AI Agent Identity AI agent identity is the practice of giving autonomous AI agents, copilots, and bots their own first-class identities — with scoped credentials, delegated authority, audit trails, and lifecycle controls — instead of letting them impersonate users with broad permissions. Last reviewed 3 months ago Key points - Treating agents as users (with the user's credentials) is the fastest way to create unbounded blast radius. - Agents need their own identity records, scoped tokens, delegated consent, and revocation paths. - Emerging patterns: OAuth on-behalf-of, scoped delegation tokens, agent-specific OIDC clients, per-agent audit. - Categories forming: agent identity platforms, scoped token brokers, agent observability, agent IGA. - Standards are still maturing — IETF GNAP, OpenID FAPI, and emerging W3C work on agent attestation. ## What is AI agent identity? AI agent identity is the discipline of giving autonomous AI agents — copilots, RPA bots, browser-using agents, LLM-orchestrated workflows — their **own** identities, with their own credentials, scopes, audit trail, and lifecycle. Instead of an agent acting as "Alice with all of Alice's permissions," it acts as "agent-7841, acting on behalf of Alice, with permission to read Calendar but not delete events, valid for 15 minutes." Why it matters: the moment an agent can take real actions (send email, move money, write to a database, call other agents), it becomes a privileged actor. Borrowed user credentials give it the user's full blast radius — which, for an admin, is the entire environment. The 2024–2026 wave of agent breaches is overwhelmingly this pattern. ## What an agent identity should have A first-class agent identity typically includes: - **A stable identifier** distinct from any human user. - **Scoped credentials** — short-lived tokens with the minimum necessary permissions. - **Delegated authority** — explicit "Alice gave agent-7841 the right to read her calendar," not implicit impersonation. - **A human owner / accountable party** — every agent has a person responsible. - **Lifecycle** — provisioned, governed, periodically reviewed, deprovisioned when the use case ends. - **Observability** — every action logged with both the agent identity and the underlying user it's acting for. - **Kill switch** — single-call revocation across every system the agent talks to. ## Why it can't just be a service account Service accounts were designed for stable, system-to-system integrations: one app talks to one other app, the same way, forever. AI agents differ because: - They're often **user-delegated**, not just system-to-system. - They make **dynamic, unpredictable** calls — you can't easily pre-declare the scope. - They **compose with other agents**, so authority can chain in ways traditional auth wasn't designed for. - They scale up and down constantly, so static credentials don't fit. ## Emerging patterns - **OAuth on-behalf-of / token exchange (RFC 8693)** — propagating a user's delegated authority to a downstream agent or service. - **Scoped delegation tokens** — bespoke short-lived tokens that encode "this agent, acting for this user, can do these specific things, until this time." - **Per-agent OIDC clients** — each agent registered as its own client, with its own credentials and scope. - **GNAP (IETF)** — a next-gen authorization protocol designed with agents and richer delegation in mind. - **Agent attestation** — proving "this token is being presented by the agent I provisioned, not a clone." ## When buyers care You need an agent identity strategy before: - Your team starts shipping agents that take _write_ actions in production systems. - Your copilots start accessing customer or financial data on behalf of users. - You start chaining agents (one agent calling another). - An auditor asks "what did this agent do, on whose authority, and how do you know?" ## Common pitfalls - **Sharing one API key across all agents.** No per-agent audit, no per-agent revocation, full blast radius. - **Using the user's session token directly.** Same problem, amplified by impersonation. - **No scope on the token.** Defaults to "everything the user can do." - **No lifecycle.** Agents proliferate, nobody owns them, nobody retires them. ## FAQ ### Is agent identity the same as non-human identity (NHI)? Agent identity is a subset of [NHI](/glossary/non-human-identity). NHI covers service accounts, workload identities, machine identities, secrets — anything that isn't a human. AI agents are a newer, more dynamic flavor that strains assumptions of older NHI tools. ### Can my existing IdP handle agent identity? Most can register agents as OAuth clients today, but features like delegated authority chaining, agent-specific governance, and agent observability are still maturing. This is one of the most active vendor categories on IDSync. ## Standards & references - [OWASP — Top 10 for LLM Applications](https://owasp.org/www-project-top-10-for-large-language-model-applications/) IDSync provides educational buyer guidance based on publicly available information, editorial review, and user-submitted data.
