Password Protecting Room Creation

I have enabled Secure Domain as per the instructions in the Handbook and I do see a password prompt in order to be the host of the meeting however as an anon user I can still go to the main page, click go, and wait for a host which takes up system resources. Random people will not be able to talk to each other with this but I want to go a bit further and not even let then click the “GO” button on the homepage or not have a new meeting generated unless they are an authenticated user. Is this possible?
