Server without keyring keeps Settings Sync secrets in memory only for its lifetime. Fix status: documented_behavior Limitations: - Strings read from the VS Code CLI Rust source (main branch) at the pinned SHA; shipped CLI may lag. - File keychain stores tokens on disk (0600); evaluate the security tradeoff. - Not reproduced in this session. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/microsoft/vscode/7fbceca31b927645eda89716dfa3459f2c938d78/cli/src/auth.rs (official_docs, 2026-09-27, documented_behavior): auth.rs: keyring ops time out after 5 seconds ('communication to the keyring can block indefinitely'); VSCODE_CLI_USE_FILE_KEYCHAIN or existing file storage selects file storage (mode 0600). - https://raw.githubusercontent.com/microsoft/vscode-docs/0db25bd8e8e2efc22ba752e44451e69c599058c3/docs/remote/vscode-server.md (official_docs, 2026-09-27, documented_behavior): VS Code Server FAQ: without a keyring, server falls back to in-memory secrets persisted only for the server lifetime. - https://raw.githubusercontent.com/microsoft/vscode/7fbceca31b927645eda89716dfa3459f2c938d78/cli/src/util/errors.rs (github_source, 2026-09-27, documented_behavior): CodeError::KeyringTimeout is declared with #[error("keyring communication timed out after 5s")] (line 491).
