# Managing Cookies -
PrestaShop uses encrypted cookies to store all the session information, for visitors/clients as well as for employees/administrators.
The Cookie class (`/classes/Cookie.php`) is used to read and write cookies.
In order to access the cookies from within PrestaShop code, you can use this:
```
$this->context->cookie;
```
All the information stored within a cookie is available using this code:
```
$this->context->cookie->variable;
```
If you need to access the PrestaShop cookie from non-PrestaShop code, you can use this code:
```
include_once('path_to_prestashop/config/config.inc.php');
include_once('path_to_prestashop/config/settings.inc.php');
include_once('path_to_prestashop/classes/Cookie.php');
$cookie = new Cookie('ps'); // Use "psAdmin" to read an employee's cookie.
```
