Every day we heard about several hacking incidents occurring globally on the online accounts, data and valuable information of the end users. Therefore, it has become a necessary step for the end users to secure all their online accounts or digital assets from different types of security threats. They need to opt for an apt security solution that can easily provide protection against security breaches occurring on the online accounts. In this regard, Two Factor Authentication is an ideal solution that secures the online accounts even if the passwords get compromised. This security method makes it extremely harder for the wrong hands, or you can say unauthorized users, to access your sensitive data and information.
More about this method
Two Factor Authentication, also referred to as 2FA, adds an extra security layer or factor in the login process to verify identity of the user who is logging in to the account. With 2FA, the end users require to provide two factors – password, the first factor, and a unique verification code or OTP (One Time Passcode), the second factor, to prove their identity in the login procedure. This unique verification code is sent to the registered mobile device of the user once he or someone else has entered the valid username and password combination associated with that account. The validity of One Time Passcode is less than a minute i.e. around 45 seconds. 2FA provides several security benefits to the end users’ online accounts and sensitive applications and data of the organizations.
One major benefit of 2FA security method is that if someone else hacks or steals your secret password, then also he can’t gain access to your online account and data. It is because he needs a unique verification code along with your secret password to log in to the account. In this way, Two Factor Authentication security method secures all your online accounts from hackers and prying eyes.
Possible authentication factors categories
Something you know (the knowledge factor) – it comprises the username, password, PIN and a secret question.
Something you have (the possession factor) – it comprises credit & debit card and mobile device.
Something you are (the inherence factor) – it comprises biometric characteristics of the user like iris, retina, face scan, voice recognition and fingerprint.
Two Factor Authentication security method includes any two of the possible three authentication factors in the login procedure.
Something you know + Something you have or Something you are = Two Factor Authentication.
2FA provides higher level of security, so every end user and organization must enable this method to safeguard their valuable data.
