Future User Access Features For Expanding Device Access

“In the future, you will be able to provision access to your Particle device to other accounts and to third-party app developers; however, these features are not yet available.”

Documentation where particle says these features are being worked on.

I’m wondering where these features live in the Particle open-source codebase? I’d like to take a look at how the API for transferring devices between uses is currently implemented and see how it’s handing off credentials to better understand what it would take for Particle to implement provisioning access between multiple accounts.

Teh way particle manages users, devices, and access is tightly coupled and I’m interested in learning best practices for managing products within an organization and end customers.
