Two Factor Authentication: It’s More Than Just Password Verification

If we take today’s rapidly increasing hacking incidents & malicious attacks on the online accounts, data and information into consideration, then the security of such accounts must be the primary focus of the end users. Generally, most of the end users globally access & secure all their valuable online accounts with using just only a single layer or factor i.e. the password. But, using just only this form of verification is not enough to protect your identity. Therefore, it is better to add extra security layers or factors in the login procedure, and ensure complete security of all your valuable online accounts from harmful external threats and malicious attacks. Two Factor Authentication is the best solution to get rid of hacking incidents, as it is more than just password-only verification.

A detail about this proven security solution

2FA (Two Factor Authentication), also referred to as Two Step Verification (TSV), is an authentication mechanism designed to give you an extra layer of security in the normal login procedure to verify your identity. This security solution is easy to use and indispensable for highly sensitive online accounts and data of the end users. Two Factor Authentication security method is more than just password-only verification in the login procedure. With 2FA, an end user requires to provide two factors – password; the first factor (something you know) and a unique verification code; the second factor (something you have), to log in to his account. The second factor i.e. a unique verification code or OTP is sent to the registered mobile device of the user whenever a valid password associated with that username is entered. This unique verification code is valid only for a few seconds. If any unauthorized user hacks your secret password, then the second factor acts as a protection layer and secures your account. It is because a unique verification code, sent to your registered mobile device, is required to complete the second step, and to gain access to the account. In this way, Two Factor Authentication protects all your sensitive data, information and the online accounts from security breaches.

Possible authentication factors used in the security system

  • Something you know (the knowledge factor) – username, password, PIN.
  • Something you have (the possession factor) – credit & debit card, mobile device.
  • Something you are (the inherence factor) – biometric characteristics like iris, retina, face scan, voice recognition, fingerprint.
  • Time and Location factors – these factors are used in defence security systems.

The combination of any two of the above-listed factors is known as Two Factor Authentication. In a simple term, something you know + something you have or something you are = 2FA.

Due to high level of security, Two Factor Authentication is being used by several online businesses, websites, apps and services that process critical information. So, the end users must enable this security method on all their online accounts to move ahead of just password-only verification.
