Definition
An open standard that gives every non-human workload (service, container, AI agent) a cryptographically-signed digital identity that can be verified without a shared secret. Instead of managing passwords or API keys, each workload can prove who it is in real time.
Why it matters
AI agents cannot manage passwords like humans can. SPIFFE provides a scalable way to give every agent a verifiable identity so systems can trust which agent is making a request and enforce policy accordingly.
