How do I exclude pages from the Members Area group?

To exclude a page you don't need from a Members Area group — Open Site Settings > Members Area > Manage members: 

Then go to the Groups tab > Pages > click “Exclude” near the orange switch:

Once you have completed all changes, we recommend republishing all pages on the website.

If you have excluded a page from a group, but you have to log in first when you go to the page anyway — be sure to check all the groups in your Members Area. Most likely, the page has been added to another group.
