The rise of cybercrime is increasing exceedingly and majority people are now becoming more and more aware of the online data security and the entire vulnerability connected to it. But not many users are as of yet aware of the two factor authentication as it is something not yet understood even though the same users use it every single day. It is a twostep authentication that does not only depend upon the username and password only and also utilizes a rare piece of data that helps you protect your account from the prying eyes.
The standard security process requires a username, password only that makes it too easy for the intruders, hackers, snoopers to hack and get away with whatever they want.
How it works?
2FA (two factor authentication) is an added layer of protection also called as multi factor authentication which doesn’t run only on password and username but also has something unique. For instance, a physical token. Username, password altogether used with a piece of rare information (known only to the user) makes it quite difficult for the prying eyes to access the user’s data.
Previously, 2FA was not a new concept but its usage has now become much more prevalent with the passage of new age that we’re living in. Google in the year 2011 stated their 2FA for their users online which was later followed by Yahoo and MSN.
Some of the drawbacks of using 2FA are as follows:
Factors may be lost:
The basic truth is that you have no suretywhether your 2FA factors would be available when needed. In majority of the cases, these factors would be available but it only requires a single mistake to lock you out of the accounts.
For example, you might be having the SMS codes as your 2ndsource of authentication. Initially, it works fine day-to-day to access bank accounts and more. Out of nowhere, you get hit with a big hurricane and left with nothing for weeks, months and more.
Sense of security – false:
Although 2FA offers added protection, the extent of this additional protection is mostly extra hyped. Most of the users would tell you how safe, solid, reliable this type of protection is, but that’s a bit far from reality nowadays.
Not perfect/room for improvement:
In case of recovery where you get locked out of a service as you lost a factor, you automatically land into a position of a hacker where you are trying to access your account with no rights. But even in such conditions, you are able to access the account without a factor. Hence, this means a hacker can also enjoy the same features as well.
Can be used against you:
2FA’s main objective is to make you safe, your data safe, your privacy safe and more. But the reverse situation can also occur where hackers can set up 2FA or reconfigure it to prevent you from accessing your very own account.
Another major drawback of this type of protection is the inconvenience of it. It’s nothing but an extra step but while you are accessing your accounts daily or weekly basis, these steps become a hectic task.
All in all, 2FA has its merits, demerits and either conditions. It would be quite easy to highlight these threats as reasons to stop using 2FA but using it just to be sure is also helpful. The drawbacks listed above are only to explain how it can backfire in certain conditions and that you are not supposed to be totally dependent upon it as there is still room for improvementinside 2FA.
