  What is two' factor authentication?

    

Passwords are everywhere. We use them to access ourmoney, on our communications, even our social lives. At first, we used onepassword for everything, but that wasn't good enough, so we started making ourpasswords even more complicated and began using passwordmanagers to organize the dozens or hundredsof the unique passwords we used, but no matter how complex our password system was, it was never enough toprevent account takeover because all it took was one phishing email or database exploit, and yourpassword was out in the world. So if passwords are impossibleto protect on your own, what do we do? That's where two-factor authentication comes in. Two-factor authentication,or 2FA, adds a second method of identify verificationto secure your accounts. First, the thing you know, your password, then something unique that you have, like your phone or fingerprint. By combining your passwordwith one of these factors, attackers can't access your account even if they have your password. The most common 2FA systemsuse a unique one time code with every log-in attempt. This code is tied to your account and generated by a token,smartphone, or sent to you by text message. The more modern andmost secure form of 2FA uses a mobile app to sendan approval notification to your smartphone or smartwatch for the least hassle possible. With 95% of breachesinvolving account takeover, two-factor authenticationis the most effective method of prevention. It's time for everybody,businesses, governments, and you to take the easy and effective step of enabling two-factor authentication on all accounts. If it uses a password, it needs to use two-factor authentication. /multi factor authentication
