Replaced New Empty Backup Authenticator

Question

Recently I lost my Phone. I installed authenticator app on a new one. I logged in but there is no restore account option. So by mistake I replaced new empty back with old backup. I lost all my authentication. After all of this I got to know that there is tiny recovery option on app starting page before login. Now I manually emailing my document to recover my all account.

Recovery option must be in setting after login because it's not noticeable on app starting page with small text.

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.
