Hi,
Thank you for the update.
Since you no longer have access to the device with the Authenticator app and do not have any backup codes/methods, here are the steps to regain access:
- If this is a personal account:
- Visit the Microsoft Account Recovery Page and fill out the form with as much detail as possible. Link -> https://support.microsoft.com/en-us/account-billing/help-with-the-microsoft-account-recovery-form-b19c02d1-a782-dee6-93c3-dc8113b20c42 Submit the request and then wait for verification.
- Contact your organization’s IT administrator. They can reset your MFA settings and provide you with new instructions for setting up the Microsoft Authenticator app.
Once your access is restored,
Configure backup methods like an alternate email or phone number.
Enable cloud backup in the Microsoft Authenticator app for future ease.
