Two Factor Authentication: It’s and Will Always Be Important

Two Factor Authentication: It's and Will Always Be Important

Using just a single authentication factor, i.e. secret password, in the login procedure leaves valuable online accounts, sensitive data and information of the authentic end users vulnerable to security threats. Taking this weakness of using password-alone protection into consideration, it is better to opt for an additional factor to ensure optimum security of your precious digital assets. Two Factor Authentication is the best and proven method that strengthens the weakness of password-alone protection, and secures your online accounts from every security breach.

What this method is and how it works?

Two Factor Authentication, or simply 2FA, is a security method that requires an additional factor; unique verification code, along with secret password in the login procedure to verify identity of the user. 2FA method provides a top-level security to the online accounts and data of the end users. Due to the use of two different factors; secret password and unique verification code, 2FA is also known as Two Step Verification.

Traditional authentication method of logging into an online account or website requires only a username and password combination. But, Two Factor Authentication security method requires you to provide a second form of validation, i.e. a verification code, to gain access. The unique verification code or OTP (One Time Password) is sent to the registered mobile phone of the user after every login attempt, and is valid only for a few seconds.

This additional validation comes in following three forms:

  • Something the user knows (the knowledge factors) – username, password, PIN.
  • Something the user has (the possession factors) – credit & debit card, mobile phone.
  • Something the user is (the inherence factors) – biometrics like iris, retina, face scan, voice recognition, fingerprint.

What does 2FA secure?

Two Factor Authentication secures all online accounts, remote access to the web applications, online checkpoints, payment gateway, etc. from different malicious activities that occur over the internet.

Possible ways that Two Factor Authentication can increase security are:

  • 2FA reduces vulnerability after a security breach. The online accounts remain protected due to the required second form of verification in the login procedure.
  • Receiving unique verification code on your mobile device warns you that someone else has attempted to log in to your online account with valid username and password combination.
  • With 2FA, your digital assets are least likely to be compromised. Traditional login credentials, i.e. secret password, can be easily hacked by the hackers, but Two Factor Authentication security method relies on something only the authentic end user has.


The importance of Two Factor Authentication security method is increasing rapidly with the increase of malicious attacks over the internet. The end users around the globe must enable this method on all their online accounts for better security.
