Two-factor authentication doesn’t need any introduction to the modern world. Digital technology is at its peak and a majority of people living in this world are already the part of this community. With more and more people joining the Internet every day, issues related to online security are also increasing. Two-factor authentication is one such thing which ensures the security of user’s identity and resources accessed by him. Two-factor authentication or 2FA is also called two-step verification or dual-factor authentication. It is basically an additional layer of security for our accounts and transactions. Almost all crypto exchanges like Kucoin, Bittrex, Hitbtc, Secondbtc, Binance Use Google Two-Factor Authentication.
Two-factor authentication is extremely secured when we compare it with single-factor authentication. Unlike single-factor authentication, in two-factor authentication, we cannot access our account knowing our username and password only. Instead, we need an additional factor of authentication that can be a security code, one-time password, biometric factor or smart cards. These additional levels of security cannot be obtained by the criminals of the cyber world as they are confined to our physical self and secured devices.
How Two-Factor Authentication works
Setting up Two-factor Authentication
While setting up our accounts anywhere nowadays, you must have encountered words like two-factor authentication or two-step verification. So, what are they? and how are they helpful in protecting user’s credentials?
Two-step authentication is a must-have requirement for every user who uses his account for various transactions or investments in cryptocurrency and exchanges. We can set up two-step authentication in our accounts online. The option for setting up two-step verification can be found while creating our accounts.

The user is provided with security codes which can be used to verify the high-security processes of our account.
Different factors for two-factor authentication
Nowadays, Banks also provide their customers with physical smart cards and verify their identity using fingerprint readers and retinal pattern scanning. There are many things which can act as the second layer of authentication. Apart from those mentioned above, the second factors in two-factor authentication also include facial scan, voice recognition, keystroke dynamics, speech patterns, Key fobs and physical cards. A majority of authorities use a one-time password to verify the user.
As the name suggests, one- time password is a unique code which is sent to the registered contact numbers or emails of the user. With the ease of setting up two-factor authentication like never before, it has gained the faith of users and has provided ultimate security to the user and resources accessed by him.

How is Two-factor authentication useful in Exchanges
Many people save themselves from investing in cryptocurrency, not because of the risk of falling down its rates in future but they fear that their funds are not secure. Two-factor authentication ensures ultimate security to your accounts in exchanges. In this digital world, our accounts are not safe with password only. These passwords can be easily acquired by hackers through our online activity, less secure and spam sites and phishing. Additionally, a password is something which needs to be remembered. One can know something that you know (username) and can get something that you have (password) but It is extremely hard to get what you mean your physical self. This is what two-factor authentication provides the user with.
Two-factor authentication makes it harder for cybercriminals to get access to user’s online accounts and devices. Even if someone acquires the password of a user, he/she will not be able to get into the account without passing the second layer of security and thus, their login will not be approved. Two-factor authentication has really brought a revolutionary change in the digital world and it has made cryptocurrency exchanges and various other types of investments and transactions safe and trusted.
