Hello
If the Microsoft Authenticator app on macOS or Windows isn’t showing the two-digit code needed to approve sign-ins, try these steps:
Update the App: Ensure you have the latest version of Microsoft Authenticator, as updates often fix bugs and compatibility issues.
Check Notifications: Confirm that notifications for the Authenticator app are enabled in your system settings, as this can prevent code prompts from appearing.
Sync Time Settings: Make sure your system clock is set to automatic or syncs with the internet, as incorrect time settings can disrupt app functionality.
Re-add Account: If the issue persists, remove and re-add the account in Authenticator.
