Microsoft Graph API, deleting authentication method "Microsoft Authenticator" Returns 400 Error

Question

Hi,

I'm attempting to delete a user's Microsoft Authenticator Authentication Method (#microsoft.graph.microsoftAuthenticatorAuthenticationMethod) from the user's list of authentication methods. However, I keep receiving the following error:

Status Code: 400, Bad Request

Error Message: Cannot delete default method with other methods configured. Please change default method before deletion.

Here is my code snippet:

async deleteUserAuthenticationMethod(email, authId, accessToken) {
    const query = `/users/${email}/authentication/microsoftAuthenticatorMethods/${authId}`

    await azure.graph.delete(query, {
        headers: {
            'Authorization': 'Bearer ' + accessToken
        }
    });

    return 'Authentication method deleted successfully';              
}

Here are all of the available authentication methods the user has set:

• #microsoft.graph.passwordAuthenticationMethod
• #microsoft.graph.microsoftAuthenticatorAuthenticationMethod

Please advise.

Thank you

Hi @Angel Fontalvo

As the error message indicates, the default method with other methods configured cannot be deleted. This error will be thrown if you are trying to remove the user's default authentication method.

You can first list all authentication methods for a user, including the default method, and then change the default method to the target method to delete other authentication methods except the default method.

Refer to similar thread: https://github.com/microsoftgraph/microsoft-graph-docs/issues/14470.

Hope this helps.
