Does FusionAuth have an equivalent to Auth0 Organizations (B2B scenario) where users can log into the same organizations as their team members (colleagues).
The best way to model that is using entity management: https://fusionauth.io/docs/v1/tech/core-concepts/entity-management
We unfortunately don't have a sample application showing this behavior, but know that folks have implemented that type of behavior using this feature.
Also invites can be sent to email addresses for pre-registered users (with configured roles) under the same organization/company.
Some FusionAuth community members use the Setup Password template (which is sent whenever a user is created via the API without a password) to offer invite-link functionality.
