Most organizations still treat credentials as something that must be protected, stored, and rotated. But a second model is quietly reshaping how machine authentication works: eliminate static secrets altogether and authenticate workloads using identity and just-in-time access.
The OWASP Top 10 for LLM Applications is the most widely referenced framework for understanding these risks. First released in 2023, OWASP updated the list in late 2024 to reflect real-world incidents, emerging attack techniques and the rapid growth of agentic AI.
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.
Choosing the right flow is only the beginning. The real challenge is implementing either flow without creating persistent credential vulnerabilities that undermine your security.
IAM migrations stall in hybrid enterprises due to massive on-prem Active Directory (AD) deployments, budget and regional constraints, and a lack of alignment among development, DevOps, and security teams.
