Hi! I think it's a nice code, but there are some things to do with it, because it doesn't do "User Auth" exactly. My questions: 1. What happens when a user tries to register himself as an existing user? mySQL only appends a new record, with an _another_ password. 2. What happens when a double-registered user tries to sign in? Whose datas will be applied? Whose password will be checked? The first of them? So please modify your code to handle these cases too, because I think this way of solving "user authentication" problems is not so secure. Happy coding to you: Yoda from Hungary

Your going to need to do a validation for a username on the registration page. Put another submit button that goes to a page that will check to see if that username is already taken. It's not that hard. You should also be able to piece it together with the code from the login.php . If you need anyhelp e-mail me at free0n@mchsi.com I can work with you and try to help you if you want. I gave it the title User Auth because it does validate the username and password. It's basically the backbone of a system. There are lots of addons you should do like text field validations. And besides where is the fun if you don't create somthing yourself. well later.
