Microsoft account as identity provider with Azure AD B2C

Question

Hello,

I am trying to add Microsoft account as an identity provider to my application, so that any one with a personal microsoft account can log in. To simplify the learning, I did the exact steps mentionned in the tutorial https://learn.microsoft.com/en-us/azure/active-directory-b2c/tutorial-register-applications https://learn.microsoft.com/en-us/azure/active-directory-b2c/tutorial-create-user-flows?pivots=b2c-user-flow.

Still, it doesn't work for Microsoft accounts. It does work for emails but not microsoft account. When I test the user flow, I get "AADB2C90273: An invalid response was received : 'Error: invalid_request,Error Description: Proof Key for Code Exchange is required for cross-origin authorization code redemption.' Correlation ID: 25c5d1b8-df10-4a52-9310-111fa518439f Timestamp: 2024-08-15 16:40:20Z"

When I added Microsoft account as an identity provider, I used the client ID of the app I created in my Azure AD B2C tenant, and the secret I generated for it.

Has anyone a solution for that ?

Hi @Omar ZERHOUNI

Thanks for reaching out to Microsoft Q&A

Based on the documentation below, you'd need to create the application object that supports "Microsoft Accounts" sign in type and configure Microsoft as an Identity Provider. The link below has all the steps you need to set this up:

Let me know if that helps.

Thanks,

Fabio

Answer 2

Hi Fabio,

I already did that. Still, Microsoft Account wouldn't work as identity provider. Only email works.

Answer 3

Sorry, I have just noticed that your link talks about Entra ID and not Azure-AD-B2C. Will the workflow enable me to use application in Azure-ad-b2c ?
