If you’ve ever swiped your bank card and then input your PIN or if you have used your credit card online and had to input the verification code to finalize the transaction, you have used MFA. Multi-factor Authentication, or sometimes referred to as 2FA (two-factor authentication), is a security enhancement that requires you to present two pieces of evidence – your credentials – when logging into a account.
Why is MFA important? According to a study, 54% of consumers only use five or fewer passwords for all of their accounts. A major issue would be caused if a hacker was able to crack your password as they would be able to access multiple of your online accounts. However, if MFA is enabled, the hacker likely would be unable to also access the second authentication factor; effectively stopping them in their tracks.
Let’s simplify this in a real world scenario. Let’s say you have a safe at home that has all your valuables in it. The safe can be opened with a key and that’s the only thing needed to open it. If someone gets that key, they are in the safe. But, let’s say that the key only opens a panel that accesses a keypad that requires a code to open it. A person would need the physical key and the code in order to be able to get the safe open. Being able to get the physical key and have the code is much more difficult to do.
MFA and 2FA is a key component of your safe and secure online experience. I would encourage you to implement this anywhere it is available to you. If you have any questions or comments, please feel free to contact me at email@example.com.
