Why isn't there Two Factor Authentication on Wallets?

[Bitcoiner2015]

Electrum has 2FA, Alts won't because they aren't nearly as developed as Bitcoin.
ETH doesn't even have a real functioning wallet!

I've seen some wallets that bring this possibility, but I think it's not easy for most cryptos... there are certainly technical obstacles, and this also brings additional costs to the developers. In addition, the wallets with two-factor authentication that I've used so far required a fee to enable this option.

No fee in BitBay to use joint accounts for 2FA

So long story short, I'm a super noob, but recently started mining and think there's a lot of potential in holding some of these alt coins for the long term.

Was just curious though, why isn't there two-factor authentication on any wallets? I get that there's passphrases and wallet encryption, but I haven't seen a wallet or platform that provided 2 factor with either Google or Authy.

Is that even possible?

Installing 2FA on a personal local wallet is not bright.
Most people's phone number are public info or at least very easy to find.

It gives Google or your Phone provider the ability to block your ability to transfer your coins out of your own wallet.
Bad idea, if you feel this is needed just use a bank instead because you are giving control of your money to a corporation.  


 

There is BitBay, BitHalo, BlackHalo all have multisignature wallets with automated two step send so you can send using two computers. It makes your account unhackable.
