OAuth for Agents

exe’s new Workload Identity Federation integration enables agents and workloads to access cloud resources through short-lived, narrowly scoped credentials rather than storing long-lived secrets in virtual machines. The approach builds on a model popularized by Kubernetes, where a workload receives a signed identity token from a trusted identity provider and exchanges it with a cloud provider for temporary access to an authorized service account. This reduces risks associated with leaked, untracked, and periodically rotated credential files while improving visibility into which workload is accessing which resources. exe’s implementation lets users create an Identity Federation integration, attach it to VM tags or individual VMs, and configure providers such as AWS or GCP to trust exe’s OIDC issuer. In a Google Cloud example, an agent requesting BigQuery access receives an exe identity token, exchanges it with Google’s Security Token Service for a federated token, impersonates an authorized service account through IAM, and uses the resulting temporary access token to query BigQuery.
