CLAUDE_CODE_DISABLE_LAUNCHER_SIGN_IN

Updated October 23, 2026 by Alex Sorokoletov

CLAUDE_CODE_DISABLE_LAUNCHER_SIGN_IN is a Claude Code environment variable: When set, the launcher sign-in path reports switched_off and does not offer launcher sign-in. Removed in v2.1.310, so current releases ignore it. It is not in the official reference.
