Set up a B2C tenant in Commerce

  • Article

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

Dynamics 365 Commerce uses Microsoft Entra B2C to support user credential and authentication flows. A user can sign up, sign in, and reset their password through these flows. Microsoft Entra 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.

Warning

Microsoft Entra ID 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 Microsoft Entra ID B2C.

Note

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

Tip

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