# cookieAuthentication Request Tor to bind a cookie-authenticated control port. ``` var cookieAuthentication: Bool ``` ## Discussion Maps to torrc `CookieAuthentication` (tor.1.txt). **Not normally needed** for embedded deployments: swift-tor uses `tor_main_configuration_setup_control_socket()` to obtain a pre-authenticated control socket, which bypasses cookie/password auth entirely. Set this only when exposing an external control port over TCP. Defaults to `false`. See control-spec.txt §3.5 for the cookie authentication handshake.
