In this video, I'll show you how to configure the Conference Now feature in CUCM 11.x, and I will also do a couple of demos so you can see the way this works, if you're the conference host, and if you're an attendee.
The relevant documentation which you should also review, is this:

The way you see it in the demo, is the way this currently works, this is an upgrade from the old MeetMe which a lot of people have been asking the ability to be secured with a PIN for many years. If you feel the feature needs to be adjusted, for example, lately someone was asking for alternate ways to change the Attendees Access Code when Self Care Portal was not available, get in touch with your AM/SE to submit a PER.
