Linux Debian - Secure Guest Access?

I tried looking through Google but it only returned results that seemed to match what I am looking for from 3-9 years back. I wanted to be sure what is out there is still secure and relevant.

I would like some sort of guest account that allows people to log in and check email, maybe play a game, etc., but not have real access to files. Maybe even an account that clears itself out after each logout.

Is there anything like this or is it still fairly unsecure?

Thanks,
Jonathan
