Agent Identity and Authorization in Production: Scoped Delegation, RFC 8693 Token Exchange, and Sender-Constrained DPoP Tokens
As autonomous AI agents shift from isolated experimental runtimes to multi-hop enterprise systems, identity and access management (IAM) has emerged as the primary security barrier in production engineering. Early agent architectures relied on two flawed authentication models: deploying static API keys stored in environment variables, or passing broad, long-lived user bearer tokens directly into agent execution contexts. Both approaches break down under real-world threat models. When an agent ex
