After taking rapidly increasing malicious attacks or cyberattacks into consideration, even the strong passwords are not enough to secure the end users’ valuable online accounts and data from these attacks. The hackers or intruders use every possible cryptographic technique to hack the online accounts of the end users, and they are succeeding in this activity. Therefore, it has become must for the authentic end users worldwide to use additional security layers or steps in the login procedure, so that hacking becomes the toughest task for unauthorized users. One ideal solution that ensures complete safety and security of the end users’ precious online data, accounts and information is Two Factor Authentication method.
What’s Two Factor Authentication process?
Two Factor Authentication, also referred to as 2FA, is a method that adds an additional layer of security in the normal login procedure to check whether the user, who is logging in to the account, is authentic or not. This proven security method requires two different factors – secret password; the first factor, and a unique verification code or OTP (One Time Passcode); the second factor, to verify identity of the user. Two Factor Authentication is also known as Two Step Verification method. In fact, 2FA is one of the most powerful steps that help the authentic end users to protect their valuable digital assets with perfection.
Possible factors used in the authentication process
Something you know (the knowledge factor) – username, secret password, PIN.
Something you have (the possession factor) – credit & debit card, mobile device.
Something you are (the inherence factor) – biometric characteristics such as iris, retina, face scan, voice recognition, fingerprint.
Time and Location factors.
Two Factor Authentication security method includes any two out of the above-listed possible four authentication factors, especially Something you know and Something you have or Something you are.
One of the most common examples of Two Factor Authentication security method is cash withdrawal through an ATM. For executing this (cash withdrawal) task successfully, you need your credit or debit card (something you have) and a 4-digit secret PIN (something you know). If you lack any one of these two factors, either credit or debit card, or a 4-digit secret PIN, then you won’t be able to withdraw cash even if you are an authentic user. With 2FA, the same procedure applies for the online accounts. To gain access to your online account, you need your username and password, and a unique verification code. This unique code is sent to your registered mobile device once you enter username and password combination, and is valid only for a few seconds.
If someone else hacks your secret password, then also he won’t be able to gain access to your online account, as he needs the second factor; a unique verification code or OTP, to execute this task successfully. In this way, Two Factor Authentication security method secures all your valuable accounts and data.
