phpmyadmin multiple servers

I just installed php_myadmin.  I had a very old copy and the new version is much better.  I want to be able to connect to multiple databases, but I am not sure how.  I have a reseller account, and all account are on the same server.  I connect to each database using localhost, in their own domains (same ip though).  

Also, it doesn't ask for a user name or password, don't I have to supply those?

/*
 * Second server
 */
$i++;
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'cookie';
/* Server parameters */
$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysqli if your server has it */
$cfg['Servers'][$i]['extension'] = 'mysql';
$cfg['Servers'][$i]['AllowNoPassword'] = false;
