Blockchain is a decentralized digital public ledger designed to record every data exchange on your network. Therefore, for the security of data exchange on the network, the blockchain flow is a process that verifies a user with a distributed ledger and also verifies the digital identity of the user at the same time to protect passwords and data. of the user, this process is known as Blockchain Authentication.

This article focuses on discussing the following topics in detail:

  1. Blockchain authentication examples.
  2. What is 2-factor authentication?
  3. How does 2-factor authentication work?
  4. Why is 2-factor authentication important?
  5. Blockchain for 2 factor authentication.

Examples of Blockchain Authentication

Here are the five areas where Blockchain Authentication is used:

What is 2 Factor Authentication?

2-Factor authentication provides an extra layer of security by adding one more layer of security to the existing security layer. 2-factor authentication involves the user entering the username and password combination, and instead of gaining direct access to the account, the user will be prompted for one of the following information:

How does 2-Factor Authentication Work?

A 2FA occurs in the following steps:

  1. Enter Username and Password – In this step, the user is asked to enter the username and password
  2. Validate username and password – The authentication server validates the username and password, and if the credentials are correct, then the user is eligible for second-factor authentication. 
  3. Second Factor Authentication – In this step, the user will enter details based on the chosen second authentication mechanism.
  4. Validate second-factor authentication – The authentication server will validate the additional authentication information provided by the second factor device and confirm the identity of the user.

Let’s understand the above process using a simple example where the user tries to log in to a social media account.

Step 1: Enter Username and Password: The user will enter the username and password.

Step 2: Validate the username and password: The authentication server has validated the username and password and the credentials are correct. The user is eligible for second factor authentication than PIN in this case.

Step 3 – Second Factor Authentication PIN – The user will enter the 4-digit PIN.

Step 4 – Validate Second Factor Authentication – The PIN entered will be verified by the authentication server and if correct, the user will be granted access to the account.

Why is 2-Factor Authentication Important?

There are several benefits to using 2-factor authentication:
