Two-Factor Authentication: A New Face of Authentication!

The data breach occurred at Yahoo last year once again raised an important question in front of the digital world, “how secure is users data”? Well, explaining the answer is tough because no one knows a perfect solution. But that doesn’t mean IT experts are not trying anything, every day they come up with new solutions and methods to minimize these incidents. One of the most common approach keeping ourselves secure from external threats was keeping complex and lengthy passwords. But, today the approach is not fruitful, hackers can hack our passwords no matter how complex they are. So, we need a solution that is not hackable and keeps our resources secure.

One such solution that IT engineers came up with is double layer authentication that is two-factor authentication method. As the name suggests, 2FA completes the authentication process in two steps.

First step: In this step, users need to enter their username and password or any other way of authentication to move to next step.

Second factor: Once the user is done with credentials, a verification link or code is send to him. Users need to verify themselves to get the final permission of accessing resources.


Why second factor?

As I stated earlier, passwords alone are not safe now a days. Hackers can guess or hack passwords and get the right to access resources that belong to us. The second factor provided an extra security layer to the resources. Access to the second factor belongs only to us. Passwords might be hacked, but it is very hard to crack the second factor.

Generally, phone verification and OTP verification is considered as the verification element for the second factor. When we have to transfer money using our net banking we have to verify ourselves. An OTP is sent to a registered mobile number that we have to enter within a limited span of time to verify ourselves. Hackers can hack your net banking password but still, they are can not able to make any transaction.
Two-factor authentication is emerging as a new face of authentication and why not, the method safeguards resources in the best way. To improve more security, many businesses are implementing multi-factor authentication also.
