What is M2M authentication?

This episode of Techsplainers explores machine-to-machine authentication and explains why it has become a foundational control for modern runtime security. As nonhuman identities continue to multiply, computer systems need a reliable way to verify which workloads are actually making requests before any data, service or infrastructure action is allowed. The episode walks through how M2M authentication works across workload clients, credentials, identity providers and resource servers. From there, the discussion looks at common M2M authentication patterns. Along the way, listeners learn the benefits, tradeoffs and best-fit scenarios for each pattern, along with why short-lived, verifiable machine identity is so important for zero trust, least privilege and safe automation at AI and cloud scale.
