User profiles contain username, password, and the web pages that the user can access.

Select an existing user or create a new user, grant access to web pages and input username and password.

Remember that the username and password you input here will be handled by Microsoft Logon technology meaning that you can use easy passwords but it's still recommended that you use at least 6-digits passwords.

You can limit access to your web site to as far as one page per user.
