Azure Active Directory B2C is a new enterprise-grade, multi-tenant, cloud service that provided a secure cloud identity platform for consumer-facing applications, supporting authentication and management of consumer identities.
The new service is based on open-standards and provide cross-platform support, adding modern identity and security capabilities to iOS, Android, Windows, and browser-based applications and services.
Using Azure Active Directory B2C allows consumers to sign-up for your applications using their existing social accounts (Facebook, Google, Amazon, LinkedIn) or by creating new credentials (email address & password or username & password).
Azure Active Directory B2C can be purchased either on an Microsoft Enterprise Agreement or via Azure Direct.
The usage in the service will be billed monthly based on the total number of both:
- Stored Users: Users stored in the Azure AD B2C directory
- Authentications: Tokens issued either in response to a sign-in request initiated by a user, or initiated by an application on behalf of a user (e.g. token refresh, where the refresh interval is configurable).
The per application Multi-Factor Authentication option can be enabled for a separate fee.
The service is currently in preview, and during the preview period, the service will be free.
