Comment (by wagon):

 What type of authentication do you suggest when tor is controlled from
 another physical or virtual machine? Should user copy a cookie file over
 network each time tor process is restarted and, hence, its cookie file
 recreated? Password authentication was a good compromise in such cases.
 `tor-prompt` already supports password authentication, but it asks for a
 password interactively. You could add `-p` option to get non-interactive
 passwords, but then password may leak through a list of processes like
 `ps`. So, I'm not sure we can resolve it securely without adding
 configuration file.
