It's not very common that you use XForms to create system forms (such as a login functionality).
Do you need to store the posted data somewhere? Does the editor need to add or edit fields in the form?
If not, isn't it better to create a custom form for that?
If you still have the need to use XForms I think it would be best to hook up to the Submit Events in XForms. For example Before or AfterSubmitPostedData
