Authorization Core vs. Authorization Extension

Auth0 currently provides two ways of implementing role-based access control (RBAC): our Core implementation and our Authorization Extension. Our Core implementation improves performance and scalability.

We recommend using Authorization Core for most implementations. If you are looking to represent teams, business customers, or partners in a B2B or SaaS application, we recommend representing them as Organizations and using Authorization Core. The Authorization Extension does not have support for Organizations.

To help you decide which feature is right for your implementation, we present the differences between the two:
