With increasing usage of the internet and every business turning online, the hacking incidents on the end users’ online accounts and confidential data, and servers of the enterprises have become too common. By default, every end user logs in to his online account using username and password combination. But, the password, being a single factor of authentication, does not provide a high level of security to your online accounts and confidential data. It (password) can be easily guessed or compromised by the hackers using advanced cryptographic techniques. Therefore, it is must for every authentic end user worldwide to rely not only on just password to access their accounts, and use an additional security layer in the login procedure. One key solution that strengthens the security level is Two Factor Authentication. So, enable this ideal method for not being hacked.
An overview of Two Factor Authentication
Two Factor Authentication, also known as 2FA or Two Step Verification, is an authentication mechanism, or you can say security method, that uses an additional layer of security in the login procedure to check whether the user, who is logging in to the account, is authentic or not. In simple words, this security method adds an additional authentication factor to verify identity of the user.
2FA security method is more than just password-only verification and requires a unique verification code or OTP (One Time Passcode) as a second factor. The verification code is sent to the registered mobile device of the user after entering valid username and password combination, and is valid only for a few seconds.
Two Factor Authentication security method, as the name suggests, uses two out of any four possible authentication factors that include:
The knowledge factors (something you know) – username, password, PIN.
The possession factors (something you have) – credit & debit card, mobile device.
The inherence factors (something you are) – biometric characteristics like iris, retina, face scan, voice recognition, fingerprint.
Time and Location factors
The most common example of Two Factor Authentication security method is cash withdrawal through an ATM using your credit or debit card. If someone else steals your credit or debit card (something you have), then he can’t withdraw cash, as he needs a 4-digit secret PIN (something you know) to complete the transaction successfully. In the same way, if any unauthorized user manages to guess your secret password, then he can’t access your 2FA-enabled online account, as he requires your registered mobile device for receiving unique verification code to access the account. Due to the involvement of two factors in the login procedure, Two Factor Authentication method provides additional security to your online accounts and data.
