Claude Code’s OAuth login service was unavailable for more than twelve hours on Tuesday, leaving thousands of developers unable to sign in with their Microsoft or Google accounts. The outage, first reported by users on GitHub and Reddit, manifested as a “timeout” error on Windows machines and prevented the launch of any Claude‑Code‑powered IDE extensions. Anthropic’s status page confirmed the incident at 08:17 UTC and posted a resolution timestamp of 20:45 UTC, citing a “misconfiguration in the token‑exchange endpoint” as the root cause.
The downtime matters because OAuth is the default entry point for Claude Code’s cloud‑based coding assistant, which many teams have integrated into Visual Studio Code, JetBrains IDEs and custom CI pipelines. When the flow fails, developers are forced to fall back on API‑key authentication—a step that bypasses the single‑sign‑on convenience and can expose token management overhead. The interruption also highlighted a broader reliability concern: Claude Code’s recent rollout has already drawn scrutiny over “invisible tokens” that silently consume usage limits and the platform’s aggressive rate‑limiting policies, topics we covered in our April 14 pieces on Claude Code’s token handling and RAG pipeline redesign.
What to watch next is Anthropic’s response. The company has promised a post‑mortem and a hardening of the OAuth gateway, including redundant token‑exchange servers and clearer error messaging. Developers should monitor the Anthropic status dashboard and the upcoming “Claude Code 2.0” roadmap, where a native password‑less login and optional SSO federation are slated for Q3. In the meantime, teams that rely heavily on Claude Code are advised to keep API keys on hand and to test alternative authentication paths to mitigate future disruptions.
