Wombat comes with a full featured and flexible user account system. Users may register online, confirm and activate their accounts automatically. As well as login and request password renewals (in case the password was lost).
Most features are implemented in Content Component Login glued together with a bunch of event handlers. This way you can plugin or remove handlers wherever you like. Thus it is possible to setup user registration and account confirmation as an automated process, but activate accounts manually.
Users are used pretty much everywhere. Hence Wombat includes database user management. Still, user backend classes are driver based, therefore it is very easy to connect Wombat to a completly different system that provides user accounts.
