is it possible to configure XenForo so that the default registration is disabled, but an external service can tell XenForo to send someone an email with some sort of registration link. Directly creating an account and sending a randomized password that should (or preferably has to) be changed later is also ok. Since I assume that there is no way to get XenForo to do that on it's own, are there any plugins which have this functionality?
If that is not the case, is there a way to do something like adding a user to XenForo's database and immediately triggering a password reset?
Thanks for your help
