Two-factor authentication (2FA), which adds an additional layer of security, provides you with greater protection against online threats. A hacker attack happens every 39 seconds on the planet. Passcodes should be sent to your phone. However, new keys and applications may make it easier and safer.

Sounds crazy, right? It’s common to see stories about users whose accounts were hacked in today’s digital world. Online security is a priority. cybersecurity is more than one layer. Even though a complex password can protect your data well, it is still possible to crack it.

You may want to enable additional security features when using popular social networking apps and software applications. This is often known as Multi-factor authentication (MFA) or Two-factor authentication.

What is Two-Factor Authentication and how does it work?

Two-factor authentication (also known as two-step verification) is an additional layer of security that protects your online accounts.

Instead of using a single factor to verify your identity (e.g. a password), you can use two: your password as well as an One-Time Password (OTP) that you receive via SMS or email.

Let’s take a look at an example that will help you understand. What are the requirements to log into your email account

  • Your email id
  • Your password

This is called Single Step Verification. We simply need to enter the credentials and log into our account. This process can be dangerous, however. Anybody can access your email address. If your password is not strong enough, hackers can access your account. You’re in serious danger if your password is “123456”.

2FA was born. Your password and email address will not allow anyone to access your accounts. 2FA provides an additional layer of security. It requires you to submit a set credentials to which only you, as the legitimate user, have full access. This will prevent unauthorized persons from accessing your sensitive data.

Two-factor authentication is now available on many famous websites and services to provide secure logins.

What is 2FA?

Although different 2FA methods use different processes, they all follow a common workflow.

Usually, a 2FA transaction goes as follows:

  • To access the website or services, the user must enter their login credentials.
  • An authentication server verifies the password and, if correct, the user can proceed to the second factor.
  • An authentication server gives the user a unique code for their second-factor device.
  • The user confirms their identity by confirming the additional authentication.

Multi-factor authentication’s core processes are generally the same for all providers. However, there are many different ways to implement it and not all approaches work equally. Let’s take a look at different types of 2FA.
