Valuable Lessons I’ve Learned About Options

Helpful Descriptions of Different Kinds of Two-Factor Authentication In this day and age, with so many people doing so many things online, personal security is of the essence. One way companies help to keep their users’ personal information secure online is by using two-factor authentication. You’ve probably used two-factor authentication, or 2FA, on a regular basis without even realizing it. 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 prevalent example of two-factor authentication happens at a bank ATM, no matter where you happen to be. When you put your debit card into the machine, it functions, so to speak, as your login information. 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. The remainder of this guide will teach you about some forms of two-factor authentication you’ve likely seen on the web at some point in time, or are sure to see in the future.

In certain situations, you’ll type in your username and password, then be asked to let the company’s server text message you a one-time use password. This provides the system with proof that you have access to the phone number that is on file for you; a thief, in almost one-hundred percent of situations, wouldn’t be able to do this. The single downside of one-time use SMS passwords is that people who only have landlines can’t use them.

Login Verification Is an Excellent Choice If you’ve ever registered for a website where you have to enter answers to security questions, such as what street you grew up on or what your dog’s name is, you’ve probably used login verification at some point in time. 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 downside to this is that, at least in theory, a thief could know the answer to your personal question, even though it isn’t 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.
