Set up a B2C tenant in Commerce

This article describes how to set up your Azure Active Directory (Azure AD) business-to-consumer (B2C) tenants for user site authentication in Dynamics 365 Commerce.

Dynamics 365 Commerce uses Azure AD B2C to support user credential and authentication flows. A user can sign up, sign in, and reset their password through these flows. Azure AD B2C stores sensitive user authentication information, such as username and password. The user record in the B2C tenant will store either a B2C local account record or a B2C social identity provider record. These B2C records will link back to the customer record in the Commerce environment.


Azure AD B2C will retire old (legacy) user flows by August 1, 2021. Therefore, you should plan to migrate your user flows to the new recommended version. The new version provides feature parity and new features. The module library for Commerce version 10.0.15 or higher should be used with the recommended B2C user flows. For more information, see User flows in Azure Active Directory B2C.


Commerce evaluation environments come with a pre-loaded Azure AD B2C tenant for demonstration purposes. Loading your own Azure AD B2C tenant using the steps below is not required for evaluation environments.


You can further protect your site users and enhance the security of your Azure AD B2C tenants with Azure AD Identity Protection and Conditional Access. To review the capabilities available to Azure AD B2C Premium P1 and Premium P2 tenants, see Identity Protection and Conditional Access for Azure AD B2C.
