What Is 2FA? How To Use It & Secure Your Account


Work on the Internet is always associated with the risk of leakage of personal information and the loss of digital assets as a result of hacking of trading platform accounts and electronic wallets. Regardless of the level of complexity of the password you have created, it is better to have a second level of access control, so you will greatly complicate the life of hackers. The 2fa code generation program would be a good option for this.

Probably there is not a single cryptocurrency service or exchange that would not recommend its customers to activate additional account protection using Google Authenticator. Setting this option is sometimes a prerequisite. And rightly so, it is better to let the user use the 2fa code than lose his crypto coins. After all, if an attacker breaks the password of your account on the 2fa crypto exchange, this is the only barrier between him and your deposit.

In cryptocurrency services, customer money is protected by a multi-level security system, and two-factor authentication – Google Authenticator is an integral part of it. If you come across an exchange on which this function is not provided, then run from it without looking back. What is the application for 2fa code and how is it configured, we will now tell you.

What is 2FA Security?

2FA stands for two-factor authentication or two-step verification. Two-step verification is exactly what the name says: two forms of identification instead of one. So instead of just a password, you now also enter a code that will be sent to your mobile phone.

How does two-step verification work?

The first step is always the same: to log in, enter your username and password, as you always do. New is the addition of a second step, where you enter a code that you receive via your mobile phone.

After entering your code, the service recognizes your PC, tablet, or mobile as a trusted device, so you don’t have to unlock a double lock again in the future to log in.

How do I Enable 2FA?

One of the most common forms of 2FA on cryptocurrency exchanges is the one with a 6-digit code obtained through a free app. If you have a smartphone, we advise you to use Google Authenticator  (Android, iOS) or Authenticator (Windows Phone); apps that produce offline codes for use when you are not at home. Other apps like Authy can also be used. If you are using another app, see the instructions for that app for help setting up the 2FA. Google play store Apple app store

How to restore Google Authenticator? What to do if the phone is lost?

If you have activated two-factor authentication, then, having lost your smartphone, you will lose access to your account. We wrote down the 16-digit 2FA key – great, there is no problem.

Download the two-factor authentication program to another device and add the account manually. But if your recovery code is much more complicated. Users who have passed full verification on the exchange can contact the support service and there they will be explained to them how to restore Google authenticator. Well, if you work incognito, then reset Google authentication settings, as follows:

  • Open the login page.
  • Enter your email address and password.

Important!  Now you have to go through complete identity verification and only after that you can reactivate the two-factor. Until you do this, your exchange deposit will be blocked.
