It has been posted in the past, but not to let things go under:
We urgently need a user login/OAuth component for Joomla, like you (Patreon) publishes for WordPress. Joomla is one of the largest CMS in the world, and it offers flexibility and more “real” CMS features (like modules, better category handling, etc) in comparison, that’s why modern websites are often built on it.
Please, @Pateron put the porting/development of a user login component on the to-do list and support creators better by that. It is never good to be only one-sided.
