Use Cases for Microsoft Entra External ID

Customer Identity Management

Microsoft Entra External ID serves various use cases, making it a versatile solution for organizations. One of the primary applications is Customer Identity and Access Management (CIAM). This approach allows you to manage customer identities effectively while ensuring security and compliance.

Manufacturers also leverage Microsoft Entra External ID for secure access to supplier portals. They can implement federated login support for large partners and apply Conditional Access for compliant devices. This ensures that only authorized users can access sensitive information.

SaaS providers integrate Microsoft Entra External ID into their applications. This integration enables business customers to register new users and manage access efficiently. By focusing on product features rather than security infrastructure, these companies can enhance their offerings.

Business-to-Business (B2B) Collaboration

Microsoft Entra External ID excels in B2B identity scenarios. It supports user flows that define various sign-in methods and external identity providers. Here are some key features:

• Microsoft Entra ID federation enables seamless B2B collaboration.
• Business partners can onboard via Entitlement Management, self-service sign-up, or invitations.
