You want to edit this file:
“\xampp\phpMyAdmin\config.inc.php”
change this line:
$cfg['Servers'][$i]['password'] = 'WhateverPassword';
to whatever your password is.
If you don’t remember your password, then run this command in the Shell:
mysqladmin.exe -u root password WhateverPassword
where ‘WhateverPassword’ is your new password.
