How to reset a user password with the WordPress Toolkit
To begin, you need first to login to your cPanel and navigate to the WordPress Toolkit link under the WordPress Tools tab.
Now, locate the site you want to reset the password for and click on the Manage button next to it.
A new page will open where several buttons will be presented. Click the Reset Pass button.
A new pop-up will appear in which you can choose from the available usernames in your WordPress from the Username drop-down field. Then input the desired new password for the user and click Continue to apply it. Make sure to always use a strong password for all users on your website.
That's it, you can now login with your new password.
How to reset a user password manually via phpMyAdmin
As an alternative to using the WordPress Toolkit tool in your cPanel, you can reset the password for a desired user by changing it directly in the application's database. To do this, go to your cPanel and click on the phpMyAdmin icon in the Databases section.
Next, locate your WordPress database from the list on the left.
If you're not sure which one it is, you can check the wp-config.php file in the root folder of your WordPress installation for the line below:
Next, click on the SQL link in the top menu.
On the new page that opens, you need to enter the following MySQL query inside the text field in the page:
UPDATE `wp_users` SET `user_pass` = MD5('NEWPASSWORD') WHERE `wp_users`.`user_login` = "admin_username";
In the above query replace wp_ with the actual table prefix for your WordPress, NEWPASSWORD with the desired password and admin_username with the actual WordPress username. Once you do that click on the Go button in the bottom right part of the screen to execute the query.
You can now login with your new password.
