I would like to test appengine. At this moment it is not clear to me if there are libraries that support custom authentication. I want the user to be able to create an account on the site without having to have a google (or any other) account.
Does that kind of libraries exists or do you have to write it from scratch? Can anyone provide me with some step by step example? (if such library exists of course..)
(I would like to use Java if possible)
Thanks!
