Definition
A standard for issuing cryptographic identity documents (SPIFFE verifiable identity documents or SVIDs) to AI agents and non-human workloads, enabling strong authentication without relying on API keys or static credentials. SPIFFE decouples identity from infrastructure.
Why it matters
Traditional API keys and static credentials are inadequate for autonomous agents that spawn dynamically at scale; SPIFFE provides a foundation for zero-standing-privilege access, allowing agents to prove identity without storing long-lived secrets.
