If you are unable to access your Microsoft Authenticator app because it is still linked to your old phone, you will need to reset your multi-factor authentication (MFA) settings. Here are some steps you can take:
- Use Backup Options: If you set up alternative verification methods (like SMS or email), try using those to access your account.
- Contact Support: Reach out to your IT support or the Microsoft support team to reset your MFA settings. They can help you regain access to your account.
- App Passwords: If your organization allows app passwords, you might need to set one up for applications that do not support modern authentication.
- Reinstall the App: If you regain access to your account, consider reinstalling the Microsoft Authenticator app on your new phone and reconfiguring it for your accounts.
Make sure to follow the steps provided by your organization's IT department to ensure a smooth recovery process.
