Non-Human Identity

Non-human identity has become a more important term because modern environments rely on large numbers of identities that are not tied to a person. The term becomes useful when it clearly distinguishes those identities from human users while still showing why they matter to security teams.

What is Non-Human Identity?

A non-human identity is a digital identity used by software, workloads, services, applications, scripts, bots, devices, or infrastructure components rather than by a human user. These identities still need authentication, authorization, governance, and security controls because they can create significant access risk.

Key takeaways

Non-human identity is broader than machine identity alone.
These identities often carry permissions, secrets, and service-to-service trust relationships.
The term matters because their scale and sprawl create real security exposure.
If the definition treats them like standard users, it misses the point.

Common mix-ups

Using non-human identity as a synonym for one narrow product category only.
Treating service accounts, workload identities, keys, and bots as if they are all identical.
Assuming identity risk only matters when a human logs in.

Why the term became more important

Modern systems rely on automation, orchestration, APIs, agents, containers, and service-to-service communication. That means access decisions and trust relationships increasingly involve identities that are not people but still act with real permissions.

As those identities multiplied, teams needed clearer language for describing their ownership, lifecycle, and security risk.

What usually falls under non-human identity

The term can include service accounts, workload identities, application identities, automation credentials, and other machine-driven identities. The exact taxonomy differs by environment, but the core point is that these identities can authenticate and act inside systems without a human typing credentials each time.

This is why strong definitions focus on access and trust relationships, not just on naming another identity subtype.

Service and application identities
Workload-linked identities
Automation and orchestration credentials
Access paths that operate without direct human interaction

How to explain the term cleanly

Useful explanations of non-human identity make the security stakes visible. The issue is not only that these identities exist. It is that they accumulate permissions, secrets, and trust paths that can be hard to inventory or govern cleanly.

That framing also makes it easier to separate the broader category from related terms like workload identity or privileged access management.

The term is clearer when the nearby language is clear too.
