Two-factor authentication

Two-factor authentication is basically a security mechanism or technique that protects your sensitive data from hackers and misusers. As we know how easy it is to steal passwords nowadays, it’s no surprise that corporate data breaches happen almost daily. And when they do, two-factor authentication is the best way to protect your sensitive data from being stolen.

 Two-Factor Authentication abbreviated as 2FA adds an additional layer of security to your online accounts. As indicated by the name 2FA protects your account via two factors i.e. not just your username and password are there to protect your account but even after entering the password, you have to enter the OTP or the one-time password sent to your mobile which is registered with your account. It’s like two gates guarding your account. This OTP is a second credential other than your password which is generally sent to you over a device that belongs to you, to ensure the security of your account. 2FA  makes it impossible for hackers to access your account using the stolen password and login information because the second login credential is with you always and is hard to be stolen.

 Types of two-factor authentication

• Additional login credentials are known only to the account holder. This includes things like security question answers and PIN numbers.
• Devices the account holder owns that receive additional login credentials. This most commonly takes the form of a security token, mobile phone app, or tablet device app.
• Biometric login credentials are unique to the account owner. This includes retina scans and fingerprints.

Most companies prefer the device method because sometimes employees feel biometric options violate their privacy.
