Open the file C:xamppphpMyAdminconfig.inc.php in your favorite text editor. Search for the string:
$cfg['Servers'][$i]['password'] = ''; and change it to like this,
$cfg['Servers'][$i]['password'] = 'password'; Here the ‘password’ is what we set to the root user using the SQL query.
$cfg['Servers'][$i]['AllowNoPassword'] = false; // set to false for password required
$cfg['Servers'][$i]['auth_type'] = 'cookie'; // web cookie auth
