Workload Identity
Workload identity gives applications, services, containers and functions their own cryptographic identity so they can authenticate to other systems without hard-coded secrets or API keys. Standards like SPIFFE/SPIRE issue short-lived, automatically rotated credentials based on what the workload is, not a static password. It is foundational to Zero Trust and cloud-native security, where ephemeral workloads appear and disappear faster than humans can manage keys.
Definition
Identity assigned to a workload (container, function, VM, microservice) for authentication to other services and resources. Eliminates long-lived secrets — the platform issues short-lived tokens based on workload attestation. Major implementations: AWS IAM Roles for Service Accounts (IRSA), Azure Workload Identity, GCP Workload Identity Federation, SPIFFE/SPIRE (CNCF, cross-platform).

Frequently asked questions
What problem does workload identity solve?
It removes long-lived secrets from code and config. Instead of shipping an API key, a workload proves what it is and receives a short-lived credential, so there is nothing static to leak or rotate manually.
What is SPIFFE/SPIRE?
SPIFFE is a standard for workload identity (the SVID document); SPIRE is its reference implementation that attests workloads and issues short-lived certificates or JWTs. Together they provide platform-neutral workload identity across clouds and Kubernetes.
How does workload identity relate to non-human identity?
Workloads are a major category of non-human identity. Workload identity is the mechanism that authenticates them securely; NHI governance is the broader practice of discovering, owning and least-privileging all such accounts.
