I have a solution based on an IoT PaaS that provides oauth2 and openIDC client functionality, but not provider functionality. I want to make an Alexa Skill and that requires oauth provider-side funtionality. Can I use Auth0 to host a login page, check entered credentials against my IoT platform in real-time, issue authorization codes/access tokens/refresh tokens based on that initial auth with the IoT platform?
If this is not possible as described, how close can I get? Maybe after a user migration/sync I can use Auth0 exclusively in this flow?
