A non-human identity, also called a machine identity, is any identity assigned to software rather than a person, including services, scripts, devices, and AI agents. AI agents are a fast-growing category of non-human identity, and organizations increasingly need to authenticate, authorize, and audit them with the same rigor traditionally applied only to human identities.
Frequently asked questions
Are all non-human identities AI agents?
No, NHI is the broader category; it also includes services, scripts, and IoT devices that have never involved AI.
Why are AI agents treated as a distinct subset of NHI rather than just another service account?
Because agents act with delegated authority from a specific person, requiring consent and audit patterns that standing service accounts don't need.
