How Two Factor Authentication Is Better Than One Factor?

How Two Factor Authentication Is Better Than One Factor

The security of the online accounts has become the primary focus of all the end users. It is due to the reason that the cyberattacks on valuable online data, information and accounts of the end users are increasing at a rapid rate. The hackers adopt the latest cryptographic techniques to guess your secret passwords, and hack all the accounts. As you know that the password is a single layer of security that protects your accounts from unauthorized access, therefore it’s must to secure your secret password. By default, the end users require username and password combination to log in to their online accounts. This type of login procedure i.e. using just only password to verify identity of the user is known as 1FA (One Factor Authentication) or Single Step Verification. Imagine the situation that if someone else manages to get your secret password from any source, then your valuable online accounts are no longer secure. So, it would be better to opt for a security solution. One best option in this regard is 2FA (Two Factor Authentication). Move ahead with this proven security solution to secure your digital assets.

What is One Factor Authentication?

One Factor Authentication, also referred to as Single Step Verification, is a process of verifying identity of the user and granting access to the online account based on one factor or set of login credentials i.e. the password (something the user knows). This form of authentication provides protection from identity theft until your secret password does not get compromised. Once it (the password) comes in the wrong hands, your valuable online account is no more secure. This is the major drawback of One Factor Authentication.

Username + password (something you know) = successful login.

It is the simple definition of One Factor Authentication in short.

What is Two Factor Authentication?

2FA (Two Factor Authentication), also referred to as Two Step Verification, is a security method that uses two layers or factors; password – something you know (the first factor), and a unique verification code – something you have (the second factor) in the login procedure to verify identity of the user. This security method secures all your valuable online accounts, data and information from external threats or security breaches even if your secret passwords are compromised.

Authentication factors used in 2FA security method

  1. Something you know (the knowledge factor) – username, password, PIN, a secret question & answer.
  2. Something you have (the possession factor) – credit & debit card, mobile phone or any other device.
  3. Something you are (the inherence factor) – it includes biometric characteristics of the user such as iris, retina, face scan, voice recognition, fingerprint, etc.

Two Factor Authentication uses any two of the above-listed three authentication factors to check authenticity of the user.

With 2FA, the end user requires to enter a valid password along with a unique verification code to log in to his online account successfully. This unique verification code is sent to the registered mobile device of the user at every login attempt. The validity of this unique verification code or OTP (One Time Passcode) is a few seconds. So, if any hacker hacks your secret password, then also he can’t log in to your online account, as he requires access to your mobile phone to get the verification code that is needed to complete the login procedure successfully. In this way, Two Factor Authentication security method is better than 1FA (One Factor Authentication).
