@Garcia-Santiago, Ivan
Thank you for your post!
When it comes to the Microsoft Authenticator app, if you enabled the Backup and Recovery feature you should be able to recover your account credentials, but you have to first make sure that the account you're recovering doesn't exist in the Microsoft Authenticator app. To do this, you can try deleting the app from your old device, AND tell Microsoft or your organization to forget and unregister the old device.
- To remove the app from a device using a personal Microsoft account. Go to the two-step verification area of your Account Security page and choose to turn off verification for your old device.
- To remove the app from a device using a work or school Microsoft account. Go to the two-step verification area of either your MyApps page or your organization's custom portal to turn off verification for your old device.

If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
