If you are not receiving the verification code for Microsoft Entra multifactor authentication (MFA), here are some steps you can take to troubleshoot the issue:
- Check Your Phone Number: Ensure that the phone number associated with your account is correct. You can do this by selecting Other verification options and trying again with a different method.
- Contact Another Admin: If you have access to another global admin, ask them to verify that your phone number is correctly set in your user account settings.
- Account Blocked: Your account may be blocked from using MFA. Ask a global admin to check if the Block sign in option is enabled for your account in the Microsoft Entra admin center and disable it if necessary.
- Check for Limits: Microsoft may limit repeated authentication attempts. If you have hit these limits, try to sign in again after a few minutes.
- Use Alternative Methods: If you continue to have issues, consider using the Microsoft Authenticator app or another verification method instead of SMS or voice calls.
- Check Spam/Junk Folder: If you are expecting an email with a verification code, check your Junk Email or Spam folder to ensure it hasn’t been filtered out.
If these steps do not resolve the issue, you may need to contact Microsoft support for further assistance.
