Perhaps, we can't deny that it gives protection to our wallets. However, this is not the only way it guarantee a total safety to our account/wallet, it still depends on us. But what really I can say is that the use of 2FA authentication to filter possible unpermitted access to our account makes you feel easy and gives less worry that one day these hackers will crack our keys/password. For I could say that for many years I was using this, I was safe and had no experience of being hacked, and that was because I set my 2FA for my security enhancement.
