I can't see the option: "I want to use a different authenticator app" in Microsoft 365 Admin

Problem

When configuring two-factor authentication (2FA) for Microsoft 365 Admin, the option to use a non-Microsoft authenticator app might not appear:

Solution

This issue typically arises from one of two causes:

1. Organizational policy restrictions:
   • Visit the Microsoft Entra admin center.
   • Navigate to Protection → Authentication Methods → Policies.
   • Locate Third-party software OATH tokens.
   • Adjust the policy:
     • Set Enable to No (disables associated restrictions).
     • Or, edit the policy to explicitly allow the Subble user.
   • Click Save.
2. Legacy MFA policy not configured:
   • Go to Protection → Multifactor authentication → Getting started → Configure → Additional cloud-based multifactor authentication settings.
   • Ensure the checkbox for Verification code from mobile app or hardware token is selected.

Once resolved, the option "I want to use a different authenticator app" will appear.
