What is 2-factor authentication?

Only the rightful account owner can access it thanks to the additional security measure known as 2-factor authentication. In order to access their account via this technique, the user must first input a username and password combination and additional information before proceeding.

In a simple explanation, two-factor authentication is an additional layer of protection that entails using your username and password in addition to a special code created by an app on your phone or other electronic devices.

There are many types of 2FA in use, but in general, they can be divided into 3 main groups:

  • Additional login credentials: a password, SMS, a secret question, or perhaps a personal identification number (PIN).
  • Additional login confirmations: a software token, smartphones, or confirmation from other trusted devices.
  • Biometric information: fingerprints, retina scans, etc.

Pros and Cons of using two-factor authenticators


  • Second security layer: This is a given, but it is also the most obvious advantage of using a two-factor authentication solution. It’s easier to hack in an account without any 2FA.
  • Easy to use: Most 2FAs are very easy to use. Whether a beginner to an experienced one, you can quickly complete the security steps.


  • Additional device requirements: Google Authenticator requires a smartphone to run the mobile app. When the device is lost, stolen, or broken, it is quite troublesome to recover 2FA.
  • Time: One-time passwords, which are frequently set for a specific period to expire, are affected by various variables. If you don’t use the offered code as soon as possible, it will expire. You might have to wait a bit for the new code to arrive if your cell phone’s reception is unreliable in order to log into your account.

Two-factor authentication provides an extra layer of security and adds another major obstacle to hacking a user’s account. This guarantees the continued safety and security of both your money and personal information.

So 2FA is becoming more and more important as the number of crypto crimes increases over time. Can you imagine if your exchange account has tens of thousands of dollars but only need to log in with a password to withdraw money? As long as your password is peeked by someone or copied by malware, all your assets are gone. Hackers can’t do that with accounts with F2A.

Bottom line

Now you’ve understood the important role of two-factor authentication in crypto trading and the reasons why it is commonly used among cryptocurrency exchange platforms to protect users’ assets. If you haven’t set it up for your account, it’s time to do so!


Cryptocurrencies are subjected to high market risk and volatility despite high growth potential. Users are strongly advised to do their research and invest at their own risk.
