使用Microsoft Graph API Beta获取MFA信息无返回结果求助

Let’s break down why you’re getting an empty value array even with the Reports.Read.All permission, and how to fix it:

1. You’re not filtering for your specific user (most likely cause) #

By default, the credentialUserRegistrationDetails endpoint returns all users in your tenant when using application permissions. If you’re using delegated permissions (acting as your own user), you only have access to your own data—but the endpoint won’t automatically narrow it down to you.

Add a $filter parameter to target your user principal name (UPN) explicitly:

GET https://graph.microsoft.com/beta/reports/credentialUserRegistrationDetails?$filter=userPrincipalName eq 'your-upn@your-domain.com'

This ensures you’re requesting only your own registration details, which should populate the value array if you have MFA methods registered.

2. Verify your token has the correct permissions #

Even if you requested Reports.Read.All, it’s worth confirming the token actually includes the permission. Decode your JWT token (use a tool like jwt.ms) and check:

• For delegated permissions: Look for the scp claim containing Reports.Read.All
• For application permissions: Look for the roles claim containing Reports.Read.All

If the permission isn’t present, re-consent to the application or ensure the admin granted the permission correctly.

3. Check if your user actually has MFA registration data #

Double-check your Azure AD user profile’s Security info page to confirm you’ve registered at least one MFA method (like SMS, authenticator app, etc.). If you haven’t set up any MFA methods yet, the endpoint will return an empty value array because there’s no data to report.

4. Confirm your user has the right administrative access (for application permissions) #

If you’re using application permissions, ensure the service principal has been granted Reports.Read.All and that the admin who granted the permission has the appropriate role (like Global Administrator, Reports Reader, or Security Administrator). Without the right admin consent, the permission might be granted but not fully active.

5. Beta API quirks #

Keep in mind that Beta APIs are subject to changes. While this endpoint is stable, occasionally there might be tenant-specific delays in data sync. Wait a few minutes, then retry your request with the filter applied.
