- Internal guest
Before B2B, partners were often given an account in the host tenant marked with a UserType of Guest. Such users can be invited to B2B collaboration so they sign in with credentials of their own, and their object stays the same.
- Microsoft Entra External ID
Platform for external identities from Microsoft, spanning B2B collaboration and customer (CIAM) tenants. New customers use it in place of Azure AD B2C.
- Related tenants
Part of Microsoft Entra Tenant Governance: it surfaces tenants that have a visible link to yours through B2B collaboration, multitenant apps or shared billing accounts. A tenant showing up here is not necessarily one you own.
