To protect a page, or group of pages, click on Page Settings, then click Show Advanced.
Enter a password into the Password field. Passwords are case sensitive.
The Password Page Description will display below the Password field after the Submit button.
Pages descendant from a password protected page are protected by the parent page’s password.
In the example above, users must enter a password to view the content on the Clients page. The Client A and Client B pages are also password protected because they are descendants from Clients.
