Microsoft Security | Microsoft Authenticator
A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
If your phone restarted and you can't access your Microsoft Authenticator app, you may need to follow these steps:
- Check if the app is installed: Ensure that the Microsoft Authenticator app is still installed on your device. If it was removed, you will need to reinstall it from your app store.
- Restore from backup: If you had previously set up backup for your accounts in the Authenticator app, you can restore them after reinstalling the app. Follow the prompts to recover your accounts.
- Use alternative verification methods: If you cannot access the app, check if you have other verification methods set up (like SMS or email) that you can use to sign in.
- Contact support: If you are unable to regain access, you may need to contact your IT support or follow the procedures for resetting your multi-factor authentication settings.
Make sure to keep your authenticator app updated and backed up to avoid similar issues in the future.
