Hi BilboBaggins2019,
Before I reset the the account, can I clarify what you mean when you say that you have your password file downloaded and saved?
If you mean that you have used the import/export data function to create a .json file, then yes, it can be re-inserted and re-uploaded once the account has been reset. If however, you are referring to another kind of password file, can you explain further what password file you have and where you downloaded it from? (As I don't want to reset the account if the file you are depending on as a backup won't work).
