Security of the digital assets i.e. online accounts, data and information is the top priority of every authentic end user worldwide. Most of them (end users) secure their precious digital assets from the hackers or wrong hands using just a single layer of protection; the password. But, using just password-alone protection for the online accounts and data is not enough as far as today’s increasing malicious attacks or security breaches over the internet are concerned. Therefore, the end users need to use an extra security layer or factor along with secret password in the login procedure, and take their valuable digital assets security to the next level. One ideal option that ensures the utmost protection from cyberattacks is Two Factor Authentication security method. So, go for this authentication mechanism to experience the next level security.
Defining Two Factor Authentication
When you log in to a website or an app, you typically enter the username and password combination to access your account. This single step taken by the website or app to verify your identity and grant access to your account is known as 1FA (One Factor Authentication).
When you add another factor to 1FA i.e. password-only authentication system, it is known as 2FA (Two Factor Authentication) or TSV (Two Step Verification) security method. In this authentication mechanism, the end users are required to provide an additional factor; a unique verification code or OTP (One Time Passcode), along with secret password to prove their identity. The unique verification code is sent to the registered mobile device of the user as he enters the valid username and password combination, and is valid only for a few seconds.
Possible authentication factors for verifying an identity
Two Factor Authentication, as the name suggests, uses any two of the possible four factors of authentication that are:
Something you know (the knowledge factors) – username, password, PIN, a secret question.
Something you have (the possession factors) – credit & debit card, mobile phone, key fob, security token.
Something you are (the inherence factors) – biometrics like iris, retina, face scan, fingerprint, voice recognition.
Time and Location factors – geographic location.
Benefits of Two Factor Authentication method
Today, most services focused on improving the online accounts and data security of the authentic end users have adopted 2FA as a standard method for authentication. This is mainly because Two Factor Authentication security method ensures that even if one of the factors gets compromised or leaked, the other factor prevents the hackers or intruders from breaking into your account, thereby minimizing the risk of data theft.
Below are the major benefits of using 2FA:
- Reduces operational and security cost
- Provides an additional layer of security
- Minimizes the risk of data and identity theft
Owing to the increasing risks due to the growing level of sophistication by the online hackers and attackers, security measures around the world are constantly evolving. 2FA (Two Factor Authentication) security method makes it extremely harder for the online attackers to hack your valuable online accounts. Two Factor Authentication is an opt-in security feature that can be easily enabled/disabled for your online accounts as and when you wish.
