First things first, 2FA is not as complex as anyone would think. It is one of the many ways of authorization. The underlying concept behind 2FA or two-factor authentication is to provide an extra layer of security.

Why We Need 2FA or Two-Factor Authentication?

In the old days of the internet, you would only use a “username” and “password” to log into your account, for instance, your email ID. However, when the biggest websites like LinkedIn, Twitter, and Yahoo could not protect themselves from leaked login credentials of their users, they needed a solution to overcome this problem. So, they came up with 2FA or two-factor authentication.

So what is exactly 2FA or two-factor authentication?

In simple words, when two different methods of authentication are used to verify credentials, it is known as 2FA or two-factor authentication.

Typical 2FA example

Many email service providers provide the option to the users to activate 2FA. If you have activated 2FA, you would not only have to provide your “username” and “password”, but also verify it by entering a code sent on your mobile phone, like with Google Authenticator.

Other factors that may be also deployed in 2FA include:

- QR codes or barcode readers - Biometrics - The use of physical keys - Secret questions - Email verification - Enter a TAN or PIN code

So is everyone in on the big secret of 2FA?

Well, despite the fact that Google introduced the two-factor authentication to mainstream in 2010, followed soon by Facebook, not many in the US or other parts of the world rely on it. Even interestingly, some surveys also reveal the fact that many do not even know what 2FA is or what it stands for.

Where Does 2FA Come into Play for Blockchain?

There can be many future uses of 2FA in the blockchain. However, currently, people have stored millions of dollars worth of funds in their online crypto wallets. But, most of them do not feel secure. We have heard so many stories of cryptocurrency funds stolen from the users’ accounts. Thus, when it comes to protecting your hard-earned crypto funds, it is better to be safe than sorry.
