So, if you are wondering what is Two Factor Authentication then you are at the right place. Keep reading to learn more about it!

Part 1: What Is Two Factor Authentication and How Does It Work?

Before learning what Two-Factor Authentication is, let’s talk about one-factor authentication. Basically, in One-Factor Authentication, you have to enter only username and its relevant password to log into an account. In simple terms, there is only one security measure to secure your account. On the other hand, Two Factor Authentication provides a second layer of verification.

Basically, Two-Factor Authentication (also commonly referred to as 2FA) is an extra security measure that secures your account. This process makes it harder or even impossible for hackers to gain access to your personal online accounts. 2FA ensures that only you can access your account even if someone knows your password. There are three types of credentials used for 2FA that makes it work.

  • The first is a quite common one that includes a PIN, pattern, or a password. It is basically something that you have memorized by heart.
  • The second one is something that you own. For example; your mobile phone or an ATM card.
  • Lastly, it includes something that you actually are. For instance, a fingerprint, retinal scan, voice print.

Part 2: Is Two Factor Authentication Necessary?

I can imagine that for some people 2FA might seem like a bit of a hassle as it requires an additional step in order to log onto your social accounts. But it is extremely important to know that without 2FA you will always stay at risk. When you know you have enabled it to your accounts, you will eventually remain calm and patient that your accounts are safe.

It is true that since a long time, passwords have been the only security measure for us. But it is high time we move along with the modern world. Passwords are extremely vulnerable and this leaves us no choice but to acquire two factor authentication. The reason why it is so necessary is because with its extra layer of security, it makes sure that your information is protected at all costs.

Privacy has become a big issue as technology grows. So, if you think that the process of 2FA requires a lot of your time, just know that it is worth a shot. And if you don’t do this, your information is definitely going to be at a huge risk. Therefore, I am sure your answer to what is two-factor authentication and why it is an effective access control technique is perfectly answered.
