Cookies are used by Joomla to track the activities done on the website by the user. Cookies allow the web server to go back or go forward in one page, provided there is a browser history. Some website administrators give an option for user to either turn off or turn on the cookies. Although the information stored in cookies is safe, hackers can still find their way to have access to it, but the chances are low since most of the information, especially the password users provides, is encrypted.
Cookies make Joomla a convenient and user-friendly website to use because of the easy tracking it provides.
