It's everywhere these days: 2FA (twofactor authentication). More and more, you must use something more than just a password to secure your online accounts.

And most importantly, is it that much safer? Finally, I reveal the other reason why everyone is pushing 2FA so much and it doesn't have anything to do with your security or privacy!
