Problem statement: Is it possible to “share” users between tenants? For example: I have a Dev, Staging, and Production tenants and would like all users to be read and/or written from a single source of truth.
Solution: You can accomplish this across tenants by leveraging Custom Database Connections on each tenant. These connections can point to the same shared external database.
Please note that the availability of Custom/External Database Connections varies by Auth0 plan - Included in B2C Professional, B2B Professional and Enterprise subscriptions. More information on pricing can be found here.
