Claude Code v2.1.139 11 May 2026

Cloud Gateway Authentication [Gradual Rollout]

What

Claude Code now has first-class plumbing for an enterprise Cloud gateway backend.

Usage

claude auth login
# Select Cloud gateway when that option is available for your environment

Details

Adds Cloud gateway as a distinct API provider.
Stores gateway URL/status in account and diagnostics views.
Refreshes gateway JWTs through the gateway OAuth token endpoint.
Pins and verifies TLS fingerprints on restore, warning users to re-login if trust changes.
Loads managed settings through the gateway and surfaces actionable re-authentication messages when they fail.

Evidence

Cloud gateway provider and login flow (search for "Cloud gateway", "Gateway URL", "Connected to Cloud gateway.", "[gateway-refresh] refreshed gateway JWT")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
