Authorization Core vs. Authorization Extension

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

We recommend using Authorization Core for most implementations. To help you decide which feature is right for your implementation, we present the differences between the two:

Feature	Authorization Core	Authorization Extension
Enhanced performance and scalability	Yes - See Authorization Core RBAC Limits	No - Limited to 500KB of data (1000 groups, 3000 users, where each user is a member of 3 groups; or 20 groups, 7000 users, where each user is a member of 3 groups)
