Google Appengine Authentication

Question

I would like to check out appengine. At the moment, it is not clear to me whether there are libraries that support user authentication. I want the user to be able to create an account on the site without having a Google account (or any other).

Is there such a library, or do you need to write it from scratch? Can someone provide me with a step by step example? (if such a library exists, of course.)

(I would like to use Java if possible)

Thanks!
