Here is how OWASP define it:

> Non-human identities (NHIs) are used to provide authorization to software entities such as applications, APIs, bots, and automated systems to access secured resources. Unlike human identities, NHIs are not controlled or directly owned by a human. Their identity object and authentication often work differently to human, and common human user security measures do not apply to them.
