A few weeks ago we quietly released our first step in this direction, a Single Sign-on plugin for Vanilla 2. Our plugin comes bundled with a WordPress plugin that can be used with your WordPress blog to allow your WordPress users to be seamlessly authenticated in Vanilla when they’re already authenticated in WordPress. It also makes it so that links to the Vanilla sign-in and registration pages redirect to your WordPress pages respectively.

While this is great if you are using WordPress, the Vanilla single sign-on plugin doesn’t only work with WordPress, it also works with any application out there. So, if you have a custom application, and you want to know how to integrate it with the Vanilla 2 single sign-on plugin, we’ve just published documentation to get you started.
