I've secured a new client who requires user login functionality but I've never done this sort of thing before so need some advice or recommendations of what plugins to use or if I need custom functionality.
It will be a private quiz website where invited users will be asked to log in to a website so they can complete the quiz. The results of the quiz must be stored and must relate to that users login info. I don't want to use Wordpress's built in user accounts manager because I don't want quiz participants to be able to login to the CMS.
How would I manage this, are there any good plugins you'd recommend?
