Thanks for that. That was the first thing I tried, it doesn’t work. If I set posts to a certain page the password protect doesn’t appear on that page even though it’s set to protected.
I’m using a plugin on the front end to allow users to post to the site, these posts I want to let them either automatically publish to a password protected page or I would rather certain categories of posts to be password protected (with the same password). Hope that makes sense!
