===============
Random-cookie RPC authentication
---------------------------------
When no `-rpcpassword` is specified, the daemon now uses a special 'cookie'
file for authentication. This file is generated with random content when the
daemon starts, and deleted when it exits. Its contents are used as
authentication token. Read access to this file controls who can access through
RPC. By default it is stored in the data directory but its location can be
overridden with the option `-rpccookiefile`.
This is similar to Tor's CookieAuthentication: see
https://www.torproject.org/docs/tor-manual.html.en
This allows running bitcoind without having to do any manual configuration.
