Using Vanilla credentials to log in to other site
I've found lots of documentation on how to use ProxyConnect to allow my existing site to serve as login credentials for Vanilla. But what if I want to go in reverse? That is, I already have a userbase in Vanilla, but I now want to create a new application and have them be able to log in with Vanilla.
Is it possible to create something like this that would work remotely (though at the same top-level domain)? Or am I better off trying to make an application/plugin for Vanilla itself?
