Identity and authentication

Azure Active Directory (Azure AD) critical for organizations aiming for streamlined access management. With offerings like Azure B2B and Azure B2C, Microsoft has expanded the horizons of identity management, catering to both inter-organizational collaborations and consumer-facing platforms. But as terms like ‘Azure AD B2B collaboration’ and ‘external identity solutions’ float around, the distinction between B2B and B2C can get muddled. This article delves deep into Azure AD’s offerings, demystifying the differences and guiding organizations in making informed decisions.

Feature/Aspect Azure AD Azure AD B2B Azure AD B2C
Primary Use Cloud identity provider service for authentication and authorization. Collaboration with external organizations. Allows sharing application access. Protects customer-facing applications. Allows users to sign up with email or social media identities.
Target Audience Business organizations for extending identity to the cloud and SaaS apps. Businesses collaborating with external partners, vendors, suppliers, etc. Consumer-facing applications.
Integration with Azure AD Core service. Feature of Azure AD. Separate service from Azure AD, but built on the same technology.
Authentication Provides authentication for cloud (SaaS) apps, e.g., Office 365. External users can authenticate with their own credentials (work account, educational institution account, or other emails). Allows sign-up with email or social media identities like Facebook, Google, LinkedIn.
Customization Can customize the user journey during the sign-up process for applications. Highly customizable, including branding, policies, and compliance requirements.
Security External users use their Azure AD account. No need for a new password. Handles processes like sign-up, sign-in, password reset, etc.
Use Case Example Use Azure AD to allow users to work with cloud applications. Share a skills management app with another company without deploying it on their Azure AD. Build a website for clients, e.g., a shopping site or a customer-facing CRM app, where customers can log in with their email or social media accounts.
