Claims-Based Identity

Reviewed 9 April 2026 Canonical definition

Claims-based identity is an authentication model in which an identity provider issues a token containing assertions (claims) about the subject — such as its name, role, group membership, or custom attributes. In agent systems, claims can encode agent-specific metadata like framework, version, owning team, and risk classification, giving downstream services the information they need to make fine-grained authorization decisions.
