Hi @Edgar Luevano ,
Welcome to Microsoft Q&A Forum.
It sounds frustrating to lose access to your Instagram account after reinstalling Microsoft Authenticator. Unfortunately, Microsoft Authenticator does not store your authentication codes, since these are generated live on your device, meaning if the app was uninstalled and no backup was made, the codes cannot be restored. However, based on my research, here are certain steps that may help regain access:
- Instagram’s backup codes during two-factor authentication setup can be used to regain access. These codes serve as an alternative login method when other authentication options are unavailable.
- If you don’t have backup codes, Instagram offers alternative recovery methods to verify account ownership through your registered email or phone number. You should look for options like "Try another way" or "Get help logging in" on the login page.
- If you're still logged in on another device, you can then either disable 2FA temporarily or add another method, following https://help.instagram.com/566810106808145/?helpref=uf_share for detailed steps.

Kindly be aware that Microsoft is unable to provide direct support for Instagram account issues, as Instagram is a third-party service. If you need assistance, reaching out to Instagram Support is the best approach, as account recovery must be handled through their official support channels rather than Microsoft's.
I hope these steps help you regain access quickly. Let me know if you need any further clarification.
