Using Connect to authenticate an external application

Friday, July 4, 2014

We would like to add WordPress user authentication to a PHP application that lives outside WordPress, so our WordPress users can access it securely using their blog accounts. It looks like Connect offers a way for users to log in to an app: once they've logged in and given the right permissions, their user profile data becomes available to the app. But we want to restrict access to users of our blog - we can't just let every user in. Has anybody succeeded in using Connect in that way?
