Nice info. Yeah, I use 2FA on every email and financial website which supports it. Though going forward U2F would be the norm as it won't be specific to a service provider like Google (i.e. Authenticator app). For U2F you need a USB device which acts as a key and is more safer and concrete solution than 2FA.
One good thing which most people are not aware of is; hardware wallets like Trezor does support U2F and can be used as a key. The most secure way to safeguard any crucial data you have. The only disadvantage I see is you will need to have the physical device always. I had no idea if other wallets like Ledger Nano S supports it but thanks for clarifying it.
