Microsoft Entra External ID vs. Workspace Tenant
Microsoft Entra External ID vs. Workspace Tenant
Section titled “Microsoft Entra External ID vs. Workspace Tenant”Microsoft Entra External ID is a component of the Microsoft Entra identity platform designed to manage external identities. It allows organizations to securely collaborate and engage with users outside their organization (partners, customers, and vendors) without the need for creating separate accounts within the internal workspace.
On the other hand, a Workspace Tenant (often referred to as an Entra ID tenant or home tenant) is the central tenant that manages internal users, devices, and applications of an organization, providing full access to Microsoft 365 services, Azure resources, and enforcing policies like Zero Trust.
