Know the Statistics
So now that we’ve covered why two-factor authentication is so important, you’ll want to know how to set up an easy cost effective two-factor authentication (2FA) system. Well, maybe you’re not convinced yet, but once you learn a bit more about how easy it is, I’m fairly certain you’ll want to set one up. There are many different set ups and products, but let’s keep it simple. We’ll begin with a smart card and smart card reader, much like a version of the bank card system I discussed earlier. You have a card and a PIN, and you can only access the information when you have these two factors together. Again, the something you have is the smart card (i.e. bank card) and the something you know is the password (i.e. PIN).
What is it and how do you use it?
The concept of two-factor authentication (2FA) was easy for me to grasp, but how I could use it to secure so many avenues of access was something that I didn’t fully understand at first. I had to dig a little deeper to find out what it was all about. The concept—“something you have” and “something you know”—is widely used throughout the IT security world to describe 2FA.
