Frequently Asked Questions
Why is Microsoft Authenticator not showing my verification codes after reinstalling?
When you uninstall and reinstall the app, the security tokens linking your app to your account are deleted. Your Microsoft account is still trying to send requests to the old installation.

No, if you didn't enable cloud backup in Microsoft Authenticator before reinstalling or switching phones, you will need to re-register each account manually or ask your IT admin to reset your MFA.

Open the app, go to Settings, and toggle on 'Cloud Backup' (for iOS) or 'Cloud backup' (for Android) using a personal Microsoft account to ensure seamless recovery in the future.
