Episode 43 — External Identities: B2B and B2C Explained

External identities allow organizations to collaborate securely with users outside their directory, and this episode explains how Azure supports that through business-to-business (B2B) and business-to-customer (B2C) models. In a B2B scenario, partners and vendors gain controlled access to resources using their existing credentials, managed through Microsoft Entra ID. The B2C model, in contrast, enables organizations to build consumer-facing applications that allow customers to sign in using social or local accounts. Learners will see how these capabilities support modern digital ecosystems and why they are important topics for the AZ-900 exam.


The episode also covers real-world use cases that demonstrate how external identities work. A supplier portal may use B2B collaboration to share files securely, while a retail application might use B2C to let customers log in with Google or Facebook accounts. Security considerations—such as limiting permissions, applying conditional access, and enabling multifactor authentication—are also discussed. Learners gain insight into how Azure balances openness and control, allowing organizations to extend identity management beyond internal boundaries without sacrificing security or compliance.
