Making an account system?

Hello. I have a very small amount of experience with scripting in unity, but the little experience I do have is with JavaScript. I would just like to know how to create an account system for my game (Username and Password etc.). It would be good if you could link a very EASY To understand tutorial, or if you explain yourself, make it simple. Could you also try and give me a free method as I am a single developer with no money as of this moment (I’m 13 haha).

Thanks Unity Devs!

Well you need a database online (guess you can get one free somewhere), and the the WWW Class to connect to a PHP script that will talk with your MySql database.

WWW Class: Unity - Scripting API: WWW

There are 1000’s of php and mysql tutorials on the net, just google it and learn the basics.
