If you want to reset or change xampp mysql password, or have forgot the password for accessing phpMyAdmin then just follow the below step to reset the password or change the password.

 

You can do this by two methods.

 

Method 1

The easiest way is to use the security console, which you can access at http://localhost/security/
This “console” creates a password for the MySQL user “root” and is adjusting the phpMyAdmin configuration.

http://localhost/security/xamppsecurity.php

 

Method 2

With the “XAMPP Shell” (command prompt) you can also reset the password. Open the shell and execute this command
mysqladmin.exe -u root password newpassword

 

Of course, your password should not be “newpassword”, too. In the next step you must adjust the phpMyAdmin configuration for this new password. In the file “D:\xampp\phpMyAdmin\config.inc.php” change the lines:

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

To:

$cfg['Servers'][$i]['user']     = 'root';
$cfg['Servers'][$i]['password'] = 'newpassword';

 

Instead in the XAMPP Shell, you can also change the password with phpMyAdmin, and then adjust the phpMyAdmin configuration.

I hope, it will help.
