That's how developers get access to builds. Starting in the summer, Apple is also doing a public beta, and you have to sign up at the link to get access

Edit: This is only for people who are members of the Developer Program. I only pay for iOS and I have access to OS X too so you probably only need membership from the one of the developer programs.
