Administrator's Guide

It is also possible to perform IP and domain restrictions using your
.htaccess file:
Order Allow, Deny
Deny from all
Allow from .myprestashop.com
Allow from 127.0.0.1
However, you should not put this kind of directive:
<LIMIT GET POST>
Require valid-user
</LIMIT>
Indeed, <LIMIT GET POST>
Making your PrestaShop install more secure
The recommendations below are sorted by order of importance:
1. Secure your back-office
1. Rename your /admin folder after the PrestaShop installation.
This is a must, and you actually cannot access your
PrestaShop administration if you haven't performed that
change. Make sure to pick a really unique name, ideally a mix
of letter and number, such as "my4dm1n".
2. Protect your admin folder with a .htaccess or .htpasswd file, or
ask your web host to do it for you.
3. Do not let your computer keep trace of your password (cookie
or any other helper).
