How to mark an Azure AD B2C App as Publisher Verified

I have a working Xamarin Forms app that uses Azure AD B2C to login to providers such as Microsoft, Google, LinkedIn, Apple, etc. The login process works smoothly except that I get the message "Let this app access your info? unverified". See picture below:

I know how to resolve this issue for an Azure AD application. See Publisher verification and app consent policies are now generally available

The Azure documentation clearly states that this is not supported for Azure AD B2C Apps. Is there an alternate way to get past the "unverified" messsage? This is causing a massive adoption problem for my app as downloaders are hesitant to login to an app with an "unverified" publisher.

Any and all help will be appreciated.

Solution

  • I finally succeeded in marking my Azure AD B2C application as publisher verified. Now I no longer get the "unverified" description in the access screen. To do this, I followed the instructions here:

    https://learn.microsoft.com/en-us/azure/active-directory-b2c/identity-provider-microsoft-account?pivots=b2c-user-flow#verify-the-applications-publisher-domain

    It is especially important to know that the MPN id cannot be set by a user interface but you have to use Graph Explorer to set it.

    The code below is an example of using Graph Explorer to set the MPN Id: Where appObjectId is the object id of your AD B2C App. It is NOT the app id but the object id. The VerifiedPublisherID is your MPN Id that you wish to set.

    POST /applications/appObjectId/setVerifiedPublisher 

{ 

    "verifiedPublisherId": "12345678" 

}
