Every script that require auth. has 2 lines like:
$Username = $w3t_myname;
$Password = $w3t_mypass;
Since php converts several things to variables (the data passed to the server by the browser in the cookies being one of them) the Username and Password will contain the actual username and encrypted password (if logged in). Of course you could use w3t_myname/w3t_mypass directly but in the unlikely event of the cookie names being changed, you'll have to edit in more places.
