The hacking incidents on the online accounts and sensitive data of the end users are increasing at an alarming rate. For hacking end users’ online accounts, the hackers need a single factor; the secret password. Therefore, it is must for all the authentic end users globally to use an extra layer or factor along with just password and strengthen the security level. Use of Two Factor Authentication security method solves the issues related to hacking, as it stops malicious attacks.
What this method is all about?
Two Factor Authentication (2FA) is a security method that adds an extra layer in the normal login procedure; password-only verification, to verify whether the user is authentic or not. This security method is also known as Two Step Verification. 2FA is rapidly becoming an industry standard for protecting identity of a user over the internet. Two Factor Authentication, as the name suggests, uses two layers or factors – secret password and a unique verification code, to verify identity of the user. The unique verification code or OTP (One Time Passcode) is sent to the registered mobile device of the user as he enters the correct username and password combination, and is valid only for a few seconds.
Suppose, if any unauthorized user hacks your secret password, then he can easily gain access to your online accounts and confidential data. But, with 2FA, this issue gets resolved easily. It is because for accessing 2FA-enabled online accounts, the users require secret password along with a unique verification code.
Different types of authentication factors
Below are the different types of authentication factors:
Something you know (the knowledge factors) – username password, PIN.
Something you have (the possession factors) – credit & debit card, mobile phone.
Something you are (the inherence factors) – biometrics like iris, retina, face scan, voice recognition, fingerprint.
Time and Location factors
Two Factor Authentication uses any two out of the above-listed four factors, especially ‘something you know’ and ‘something you have’. One of the most common examples of Two Factor Authentication security method is cash withdrawal through an ATM using your credit/debit card. For withdrawing cash, a user requires his credit/debit card (something you have) and a 4-digit secret PIN (something you know). Enable this security method on all your valuable digital assets to enhance their security.
