If you do not want your ProProfs site to be visible to the general public, you can restrict access to it by using the private site feature. Then anyone who navigates directly to your site’s URL would not be able to view your ProProfs site.
A user in ProProfs is someone that can log in and author help pages, administer the application, add content, and more. What actions ProProfs users can perform depends on their role. People who read your documentation logged-out (such as your customers) are called end users.
ProProfs does not have a user management system for your end users. Instead, you can use your authentication/login system via Single Sign-On (SSO) to authenticate your end users.
