You can control who can read a page using the Visibility area on the Publish module.
Public means the page is visible to anyone.
Using the Visibility options you can:
- Password Protect a Page – The page is protected with a password you set. Any reader that has the password can view a protected page.
- Make a page private – Pages marked as private are only visible to users who are logged into their account; and have been assigned the role of Editors and Administrators. Logged out users don’t see private pages.
Refer to password protect posts and pages for more information.
