Add Microsoft Entra ID as an identity provider for External ID

Microsoft Entra ID is available as an identity provider option for B2B collaboration by default. If an external guest user has a Microsoft Entra account through work or school, they can redeem your B2B collaboration invitations or complete your sign-up user flows using their Microsoft Entra account.

Guest sign-in using Microsoft Entra accounts

If you want to enable guest users to sign in with their Microsoft Entra account, you can use either the invitation flow or a self-service sign-up user flow. No additional configuration is required.

  2. Complete the publisher verification process to associate your MPN account with your app registration using one of the following options:
