What is Two-factor Authentication (2FA)?: Why do you need 2FA?

2 min readJul 20, 2022


Have you ever thought of the risk that your social media password might get stolen? Or what if somebody hacks your important accounts?

2FA protects you from all these dangers! Two-factor authentication is the process of adding another layer of security that an account holder can add to their account. It helps to protect your account from hackers by forcing them to have 2 different forms of authentication before getting access to your account. It requires a second step for verification when you log in to your account by generating an OTP (One-Time-Password).

Why do you need to enable 2FA?

When you sign in to any of your online accounts, the basic authentication level asks for the password that you have set up to log in. That is one step of verification. 2FA requires another piece of information that you have to give before getting access.

It will offer you an extra layer of protection besides passwords. The second factor is a layer of protection that makes it more difficult for cybercriminals to hack into your account. Cyberattacks are one of the three most common security incidents. This drastically reduces their chances of accessing your accounts. So, even if your password is taken or your phone is lost, the chances of someone else having access to both factors are slim to none.

There are several types of authenticators that are in use today. Some may be stronger or more complex to set up. Here are some common forms of 2FA or MFA:

  • One-Time PIN (OTP), either from an Authenticator app or hardware token.
  • A unique code from a text message.
  • Fingerprint scan (TouchID).
  • Facial Recognition (FaceID).

It gives some better protection than the simple passwords that we add to our accounts. One-time passwords are a great way to protect against password hacking. With OTP, every time you log into your account, you’ll need to enter an OTP under different circumstances.
