Hello,Here are some steps you can follow to troubleshoot and potentially resolve the issue:
- Verify the Authenticator App Setup
- Open the Microsoft Authenticator app and check if the account is still listed.
- If the account is missing, it may need to be re-added. This requires access to the QR code or the recovery setup provided when the account was initially added.
- Check Alternate Sign-In Methods
- Attempt to use a different verification method if available:
- Select the "I can't use my authenticator app right now" or a similar option during sign-in.
- Look for the option to verify via email, text, or a recovery code.
- Contact the Admin of the Guest Organization
- Reach out to the administrator of the team or institution that invited you as a guest. the admin of the guest organization can remove your MFA setup and force a re-registration. This will allow you to reconnect the authenticator app.
- Ask them to:
- Re-invite you to the organization.
- Reset your MFA settings for the guest account. This will allow you to reconfigure the authenticator app.
- Use Recovery Options
- Log in to your work account's primary organization and navigate to Azure Active Directory > External Identities to check if the guest account link is visible.
- If so, you might be able to reset the MFA settings or troubleshoot from there.
- Request Temporary Access
- If immediate access is critical, ask the guest organization's admin to grant temporary access or disable MFA for your account until the issue is resolved.
