Fix Access denied for user 'root'@'localhost' for phpMyAdmin

$cfg['Servers'][$i]['password'] = ' ';

/ **************/

Locate config.inc.php file under C:\xampp\phpMyAdmin and open it in any editor.

Find the following line:

$cfg['Servers'][$i]['password'] = '  ';

Enter the chosen password inside the quotes. Also, in order to make
localhost/phpmyadmin ask for a username and password, find the following line:

$cfg['Servers'][$i]['auth_type'] = 'config';

Change the above line to:

$cfg['Servers'][$i]['auth_type'] = 'cookie';

and so forth.
