I have Azure Function Apps protected with Azure AD B2C Authorization. But I also need to get access to some of these functions from Desktop App that has no user (without user interaction). How can this be achieved?

    Hello @Tetyana Mykhnevych

    When no user interaction is required, we use application context in that case. In such scenarios, client credentials flow is used. However, B2C currently doesn't support client credentials flow. Which means, you can't use yourtenant.b2clogin.com domain to perform client credentials flow. However, you can use login.microsoftonline.com/yourtenant for client credentials flow, which uses standard Azure AD functionality and not the B2C functionality of the tenant.

    Here is an active feedback link for this feature in B2C: https://feedback.azure.com/forums/169401-azure-active-directory/suggestions/18431254-b2c-support-for-client-credential-flow. Kindly vote for it so that product team prioritize this feature in future roadmap.
