Helpful Descriptions of Different Kinds of Two-Factor Authentication

In today’s society, where the world wide web is such a major part of day-to-day life for so many people, personal security is crucial. One of the most common things companies do to secure their users’ personal information on the web is utilize a two-factor authentication process. You have likely used two-factor authentication, or 2FA, quite frequently, without even knowing what it was. 2FA refers to the fact that an individual must input two pieces of login information in two steps to prove his or her legitimacy.

The most common example of two-factor authentication involves bank ATMs the world over. After your debit card goes into the machine, it acts, so to speak, as your username and password. After that step, you must enter your PIN number to prove that you are actually the person to whom the card belongs. 2FA is meant to weed out identity thieves and stop crooks in their tracks. As you continue looking through this guide, you will see additional information about some of the popular forms of two-factor authentication you are sure to run across online at one time or another.

Login Verification Is Another Good Option

If you have ever had to enter personal information, such as the name of the street where you grew up or the name of your dog, when you sign-up for a website, login verification is probably something you’re already familiar with, even if you didn’t realize it before now. Login verification is a process that necessitates you enter a second piece of personal information other people would not know after you’ve put in your username and password. The issue here is that, theoretically anyway, a thief could have figured out the response to the question you selected, though it is certainly not likely.

If you are the operator of a website, it is particularly important for you to grasp the intricacies of different sorts of two-factor authentication, as you will probably need to use it at some point or another to help your users feel secure when they login. If you work with a webmaster, ask him or her to help you make your site as secure as possible.
