Hotspot multiple users access with same username

Hi all,

I am trying to configure Hotspot for my caffe. My idea is to have login page with banner and login button only.
I saw that I need to add username/pass to html page so it is forwarded in background when user press on button Login, and that is clear.

The question is how to configure mikrotik to allow multiple users to login this way (use only one hotspot username),
but to limit each of them to use Internet for limited period of time, for example 1 hour, and then to terminate session.
Additionally, is it possible if they used 1 hour and session is terminated to disable login for let’s say 30 min.,
and after 30 min. allow them to login again for another 1 hour.

Please help how to configure this or provide configuration sample if someone has similiar setup.

Thanks in advance!
