In this document, you'll learn how to set up multi-tenant authentication, configure login tiles for each tenant, and use client IDs and client secrets to enable seamless login across multiple Azure AD and B2C tenants.

Prerequisites

Register a Service Principal Application:

Register a service principal application in Azure Active Directory (Azure AD) and configure it for use with EmpowerID's Azure Native Auth.

• Client Secret – You use this when setting up the Azure Native Auth OAuth app in EmpowerID.

• Redirect URIs – You set this value to the FQDN of your EmpowerID Server.

• API Permission – You grant to the service principal the neccessary Microsoft Graph API permissions for Azure Native Auth. These permissions include:

  • offline_access – Maintain access to data you have given access to

  • openid – Sign users in

  • profile – View users' basic profile

  • User.Read – Sign and read the user profile.

Configure UserInfo Endpoint

EmpowerID requires the UserInfo endpoint to retrieve user data. However, unlike Azure AD, Azure AD B2C does not support the UserInfo endpoint by default. The Identity Experience Framework must be configured with custom policies that return data through the UserInfo endpoint to enable this. Refer to the Microsoft documentation below to set up these custom policies, or check the latest guidance to configure the UserInfo endpoint correctly. https://learn.microsoft.com/en-us/azure/active-directory-b2c/userinfo-endpoint?pivots=b2c-custom-policy
