1) Login into your Hosting Control Panel and open PHPMyAdmin tool (or the tool which is used for managing databases). If you¡¯re not sure how to locate and open it, please consult with your Hosting Provider.

2) From the list in the left pane, you should select the database which you created for your Prestashop CMS.

3) You should see a list of tables that are used in the selected database, but we don¡¯t need to work with any of them directly. Click on the SQL tab

4) Now paste the following line of code into ¡°Run SQL query/queries¡± text area
UPDATE `ps_employee` SET `passwd` = MD5(¡®<_COOKIE_>password¡¯) WHERE `ps_employee`.`id_employee` = 1;

Before pressing the GO button to execute this query, you need to modify it a bit:

- replace the <_COOKIE_> with the actual cookie code, which you can find in the /config/settings.inc.php file of your Prestashop engine. In my case the value is WRhw145L5k724dJEFti0a0nHuDjC8AWvbioCWOjA2cebIbv48VjEfzX2
The code value will be different for your site, as this is unique key generated for the store during installation

<?php

define('__PS_BASE_URI__', '/gordon/presta135/');
define('_THEME_NAME_', 'theme065');
define('_DB_NAME_', 'gordon_presta135');
define('_DB_SERVER_', 'localhost');
define('_DB_USER_', 'root');
define('_DB_PREFIX_', 'ps_');
define('_DB_PASSWD_', '');
define('_DB_TYPE_', 'MySQL');
define('_COOKIE_KEY_', 'WRhw145L5k724dJEFti0a0nHuDjC8AWvbioCWOjA2cebIbv48VjEfzX2');
define('_COOKIE_IV_', 'mPBcrcuj');
define('_PS_VERSION_', '1.3.5.0');

?>

- replace the word ¡°password¡± with the new password you want to use for the admin login

The final result should look similar to the screenshot below. Note! there must be no spaces or any additional symbols between the cookie code and the password
