Secure access to the Claude Platform with Workload Identity Federation

Summary

Workload Identity Federation (WIF) is now generally available on the Claude Platform, offering a secure method for workloads to access Claude API endpoints without static API keys. Compatible with any OIDC-compliant identity provider, WIF replaces long-lived keys with short-lived, scoped credentials issued at request time. This system allows workloads to authenticate using existing identities like AWS IAM roles, GCP service accounts, or GitHub Actions tokens. The platform also introduces service accounts, enabling each workload to have its own identity, roles, and audit trail. Setup is guided via the Claude Console, and federation rules can be programmatically configured using new Admin API endpoints for large organizations, supporting fine-grained, least-privilege access.

Key takeaway

For MLOps Engineers or AI Architects managing secure access to the Claude Platform, you should prioritize migrating workloads from static API keys to Workload Identity Federation. This transition enhances your organization's security posture by eliminating long-lived credentials and provides improved auditability through dedicated service accounts. Start by utilizing the guided setup in the Claude Console or programmatically configure federation rules via the Admin API to establish least-privilege access.

Key insights

Workload Identity Federation eliminates static API keys, enhancing security and simplifying credential management for Claude Platform access.

Principles

• Workloads authenticate using existing OIDC-compliant identities.
• Short-lived, scoped credentials improve security posture.
• Service accounts enable granular identity and audit trails.

Method

A federation rule binds an external identity to a Claude service account; the platform verifies the workload's signed OIDC token, matches claims, and issues a short-lived access token bounded by the service account's roles.

In practice

• Integrate GitHub Actions tokens for CI/CD authentication.
• Configure least-privilege access using fine-grained scopes.
