Can I add “password protection” to the Categories?
Of course this is possible. You can simply add if else condition in question.php to check if question is posted in protected category.
This feature may be get added in future.

I think for that you need a meta for user, if they can access the category. So in questions you can simply check if user has that meta and that’s it.
Hmmm, the reason I need the Q & A secure is because I will implement it in a online classroom, and each category will be a different class. I will bring your answer tomorrow to my superior and hopefully they give the go to implement it.
Thanks a lot for your fast response.
