Smart Ideas: Systems Revisited


Helpful Descriptions of Different Kinds of Two-Factor Authentication In the modern world, with the internet playing such a massive role in people’s everyday lives, personal security is absolutely critical. One way companies help to keep their users’ personal information secure online is by using two-factor authentication. 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. A primarily example of two-factor authentication takes place at bank ATMs everywhere. When you put your debit card into the machine, it functions, so to speak, as your login information. Then, you have to input your PIN number to prove your identity is valid. 2FA is meant to weed out identity thieves and stop crooks in their tracks. As you read this guide, you will learn more about some common forms of two-factor authentication you’re likely to see online. Some Companies Use One-Time SMS Passwords

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 proves to the system that you have access to the phone number they have on file for you; a thief, in almost all cases, would not. The sole downside to one-time use SMS passwords is that individuals who just have landlines are unable to utilize them.

Login Verification Is Another Good Option If you have ever been in the process of registering for a website and been asked to put in information like the name of your dog or the street you lived on during your childhood, you likely already know what login verification is, even if you weren’t aware of it until just now. Login verification involves entering another piece of personal information that only you would 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 employ a webmaster, make certain he or she knows to make your site as secure as current technology will allow.
