Please help me..
Thanks in advance.............

It seems there is NO default for user root because of "using password: NO". If it needs one then it should "using password: YES". Once inside php myadmin you can change it.

Hi,
Go the installation directory from there to phpmyadmin dir then edit config.inc.php for your username and password
