Creating a user login

[andrewsmd]

I was just wondering what is a good way to set it up so users have to login? I have a website now that I need to implement a username and login and I was wondering how I should maintain their login. Should I set a session variable to something and check for that? I've never really done this so I'm open to any suggestions.

certificates would be if you are using https, whether or not you use https depends on the information you need to protect
