Now I use my wallet MEW, I have not seen a way to enable 2FA directly on this wallet, but I use this way I find quite effective, you create a wallet into an anonymous web browser, then have the keyprivate you load Using Metamask and using metamask to login to the wallet, do not log in directly on the web browser will be very dangerous, but in my opinion you should use Mycrypto wallet, this is safer because they installed directly on the desktop yours
