Yes I use 2fa, thats a very good solution for protection your acc.
The question is what kinda 2FA you prefer..!
I've a lot of problems with authenticator. I think it's something to do with my phone not syncing to that app's time even though it was set to compensate.
Can't be arsed to be locked out of some rather important sites so it's SMS for me. I've no idea whether it's more secure though.
I personally avoid Google authenticator if I have other options to use. I don't find it as secure as Sms/voice call although I have heard theories contradicting it.
