    I just didn´t understand if it´ll be generating codes all the time or only when I´m connected to my Microsoft account.Anyway every security app is welcomed.

    Great app! Really useful for account security. If there were a way to back up keys to my Microsoft account, like Bitlocker, it would be perfect.
