Internet security can no longer be taken for granted, hence the need for extra layer to beef-up the traditional internet security systems.
Two-factor Authentication System is one of the extra layers that have been employed to beef-up internet security lately. Also dubbed Multi-factor authentication, it follows on the approach to authenticate users by two or more of the three authentication factors: Knowledge factor, Possession factor and inherence factor.
The process helps to eliminate the probability that a requesting entity to a given domain is presenting false evidence of its identity.
Knowledge factor, which denotes "what the user knows" is the common form of authentication, of which the password or PIN is the typical mechanism required. The password remain one of the most susceptible components of even the most advanced security systems. And have continued to be the bane for break-ins to such systems.
But, the good news is that the major web service providers are beginning to pay attention to the extra security factors, given the proliferation of breaches on their networks by hackers. Google launched its two-factor authentication system dubbed 2-step verification early 2011 and the service have afforded users peace of mind.
Facebook followed closely on Google's heel to announce its own two-factor authentication system. While, Microsoft has recently rolled out the service to its users as well. Even Amazon web services and a host of other web companies have implemented the extra security feature.
Its now behooving on users to avail themselves of this extra layer of security to ensure that their online transactions are safe and rewarding.
