10.3. Azure AD B2C and B2B

Azure Active Directory (Azure AD) is Microsoft’s multi-tenant, cloud-based directory and identity management service, which provides a robust set of capabilities to manage users and groups. It helps implement identity and access management across apps, both on-premises and in the cloud. Azure AD extends its capabilities with two distinct services designed for specific user interactions: Azure AD B2C and Azure AD B2B. These services cater to external users, defining how businesses interact with consumers (B2C) and with other businesses (B2B), respectively.

Azure AD B2C: Identity Management for Customer-Facing Apps

Azure AD B2C (Business to Consumer) is an identity management service that enables you to customize and control how customers sign up, sign in, and manage their profiles when using your applications. This includes applications running on iOS, Android, and .NET, amongst others. The service provides authentication for web, mobile, and desktop applications and is designed to be highly available, with a global presence.

Core Capabilities of Azure AD B2C
