Prestashop : Can't access my administration back-office ( forgot my password )

Hello Prestashoppers, how is life ?? did you forget your back-office's admin password and want to retrieve it ?? Unfortunately Prestashop encrypts your passwords so that no body can hack it. and you may have installed the back office with a fake email ( just for testing ) and you forgot to point it to your real e-mail, so you can't use the ( Forgot my password ) tool in Prestashop.

What can we do now ?? Actually there is a technical solution, just go through the following steps :

1- First of all, open your "settings.inc.php" found in YOUR SITE ROOT/config/
2- Search for " _COOKIE_KEY_ ", this is a unique key for every prestashop shop , copy its value.

3- Go to PHPMyAdmin, and open your database, and view the "ps_employee" table where you will find your users and employees, you will find your email, and there is a row called "passwd", this row is where your Encrypted Password stored. Click on the Pencil image beside your user to edit it.

4- Now you can edit your password ... HOW ?? in the "passwd" Value, Paste your _COOKIE_KEY_ and then write your new password after it directly , and select "MD5" from combobox like the image :

Now you entered your cookiekey+new password like that :

as if it is one word.

5- Now you can access your back office again :) Save your new password in your wallet not to forget it again :D
