Using one Craft CMS instance as an identity provider for another?

[ericdrosas87]

I'm part of the LSST/Rubin Observatory team that has already implemented this plugin into our main PR website, and I have been tasked with looking into if we can use that main PR website as an identity provider for another site.

Use case:
We have a separate Craft CMS (let's call it the Education CMS) we are standing up and we would like to authenticate into this new Craft instance via the main PR website's JWT graphQL endpoint.

Questions:

• Is this possible with the plugin off-the-shelf? If not, how much custom development would be needed to make this work?
• We would like to maintain a separate, dedicated database for the Education CMS, if the answer to the above question is yes, will it make "duplicate" entries, one DB record in each CMS database?

Please let me know if you need more information in order to answer the above questions.
