How to grant restricted access to article authors?

Question

Joomla

Hello. Perhaps the problem is trifling, but I did not cope due to lack of experience. Created a bunch of ad sites (more than 30) and now my project is nearing the final stage, ie. to monetization. To do this, I need to create a separate section with news, where an extremely limited circle of solvent persons will have access (publication, editing, deletion, etc., etc.). The problems that I encountered are:
1) the authorization window. How to make a hidden authorization window? That is a unique link or something like that. In short, so that the average user does not know about the existence of such a window.
2) creation of the user himself with the rights to create materials. Yes, it looks like a pretty simple task, but I was not able to create a user that would only have access to one section (news). I made a user for myself, and as a result I got access right up to the Joomla admin panel.

Answer 1

create a link, add a unique alias
in jmul add a user for the group
