Anthropic adds keyless auth for Claude Platform

This is the kind of infrastructure update that matters more than a flashy launch: it lowers secret-management risk and makes Claude more enterprise-ready.

• –Workload Identity Federation removes long-lived API keys from production and CI, which is a real security win for teams running Claude at scale
• –Browser-based CLI auth makes the local developer experience simpler without forcing everyone into secret files or env vars
• –Support for AWS, GCP, Azure, and generic OIDC puts Claude in line with how modern cloud auth already works
• –The tradeoff is setup complexity: IAM, issuer, and federation-rule configuration will be more work than dropping in an API key
• –This looks like Anthropic standardizing Claude around platform-grade identity, not just model access
