It is a simple plug and play plugin for Moodle. Just install and enable and run your Moodle site worry-free.

Students will just need to choose their password during signing up or registration. That’s it. Their usernames are randomly selected. If they want, they can change them from Moodle later. At least, they do not have to go through a long process of entering unnecessary data in the sign-up form. Less the steps, less the chance of losing a student.
