Microsoft Authenticator Not working on my iPhone???

To add your Australia Government account to the Microsoft Authenticator app on your iPhone, you need to ensure that the account is properly set up for two-factor authentication (2FA) and that you have access to the necessary information to add it to the app. Here are the steps you can follow:

1. Check Account Setup: Make sure that your Australia Government account is configured to use the Microsoft Authenticator app for 2FA. You may need to log in to the account on your Mac and check the security settings.
2. Add Account to Authenticator:
   • Open the Microsoft Authenticator app on your iPhone.
   • Tap on the '+' icon or 'Add account'.
   • Select the type of account (usually "Work or school account" or "Other" for personal accounts).
   • Follow the prompts to scan a QR code or enter a setup key provided by the Australia Government website.
3. Transfer Existing Accounts: If you had previously registered the account on another device, ensure that you are using the same Microsoft account to sync your Authenticator app across devices. If the account does not appear, you may need to re-add it as described above.
4. Update the App: Ensure that your Microsoft Authenticator app is updated to the latest version. An outdated app may cause issues with account visibility.
5. Troubleshooting: If you continue to have issues, consider uninstalling and reinstalling the Microsoft Authenticator app, then re-adding your accounts.

By following these steps, you should be able to add your Australia Government account to the Microsoft Authenticator app on your iPhone and use it for signing in.
