Machine-to-Machine Authentication

Machine-to-machine authentication is the verification of one application, workload, or service by another without human interaction.

Definition

Machine-to-machine authentication refers to the trust process used when one technical component calls another, such as an application consuming an API or a service invoking a downstream workload. It relies on technical identities, tokens, certificates, or equivalent controlled mechanisms rather than end-user login flows.

The Ariovis perspective

Machine, workload and agent identities need the same fundamentals as human identities: a clear owner, controlled credentials, limited permissions, a lifecycle and traceability.

These concepts matter most inside a real project.
