I am running a website on Ruby 2.1.5 which authenticates users through Devise 3.5.6. Thousands of users for a working site I don’t want to break. Running on example.com

I want to build a quick and dirty prototype of some new functionality in WordPress. Running on subdomain.example.com.

What is the best way for both sites to share use identity information? I am fine to just redirect to Ruby for the user signup/signin workflows. But can a user signin on the Ruby site and then appear as signed in on the WordPress site?

Sorry for the vague question — just hoping there is some smooth setup for this already.
