URL Password Protection allows you to control who is allowed access to certain areas of your website. It works by password protecting specific directories so that only authorised users can view the web pages within them.
By default you are allowed to password protect 10 directories with 10 authorised users per directory.
usernames must be unique.
URL Password Protection is most commonly used to restrict access to private or paid for sections of a website. For example, you might want a members area on your website for special offers or downloads. So you might choose to protect the http://www.yourdomain.com/members area of your website.
