Recommended action: On headless hosts set VSCODE_CLI_USE_FILE_KEYCHAIN=1 for the CLI (tokens saved to a 0600 file), or run a Secret Service keyring; expect in-memory secrets on servers without a keyring. Option: Use file keychain on headless hosts [evidence: official_recommended_action] Applies when: No keyring daemon available Steps: 1. export VSCODE_CLI_USE_FILE_KEYCHAIN=1 2. code tunnel user login (or code tunnel) Expected: No keyring timeouts; login persists. Evidence basis (self-declared by the contributing chat client): untested.
