OAuth is an authorization framework that defines how to grant access. JWT is a token format that defines how to package and transmit claims. They solve different problems, and most production systems use both.
SPIFFE focuses on who a workload is. It issues cryptographic identities to services and workloads so they can prove their authenticity to each other without relying on stored secrets. OAuth focuses on what a workload is allowed to do. It defines how access is delegated and controlled when one service needs to interact with another or call an external API.

In MCP, every request comes from a nonhuman identity: an agent, server or tool. These identities don’t act under direct human oversight. They generate requests dynamically, chain operations and carry data across trust boundaries.
Single sign-on (SSO) simplifies access for human users across an organization’s approved applications. Federated identity (FI) management connects users across organizational boundaries.
This update gives every Jenkins job a real identity and automated short-lived access so teams can retire static secrets without changing how their pipelines run.
