How can I access my 2fa codes on new device

Question

I had to get a new phone when I lost access to my old device, and I can no longer sign into any of my accounts associated with Microsoft authenticator. I am using Microsoft authenticator on many websites and when I re-downloaded the app I was only able to recover my Microsoft account 2fa. There are multiple websites I no longer can sign into because I need my authenticator code that no longer shows up in the app. How do I get my other accounts to show back up? Yes I did recover account when I downloaded it, and only my Microsoft account shows up in the app. I am missing other accounts and can no longer get authentication codes for websites associated with these accounts.

You can restore from backup (assuming there was one) but make sure no accounts have been added to the newly install app. Then sign on with recovery account to do the restore.

You can recover your account credentials from your cloud account, but you must first make sure that the account you're recovering doesn't exist in the Microsoft Authenticator app. For example, if you're recovering your personal Microsoft account, you must make sure you don't have a personal Microsoft account already set up in the authenticator app. This check is important so we can be sure we're not overwriting or erasing an existing account by mistake. https://support.microsoft.com/en-us/account-billing/back-up-and-recover-account-credentials-in-the-authenticator-app-bb939936-7a8d-4e88-bc43-49bc1a700a40

Without a backup to restore from the only option is to work with each of the service provider's account recovery methods. The authenticator app is nothing more than a code generator. The two factor is turned on or off at the service provider end.
