Multi-Factor Authentication:
What You Need to Know & How to Use It

There is a good chance that you have heard of Multi-Factor Authentication (MFA) or a subset called Two-Factor Authentication. In case you haven’t heard of it, MFA is a method of confirming a person’s identity in which a user is granted access only after successfully presenting two or more pieces of evidence to an authentication system (like a login).

Another subset of MFA is two-step authentication. This is where you enter your login and password, and then the company sends you a verification code (by email, text, etc.) that you need to input into the web page in order to access the site. A lot of banks use this type of authentication.

But why do you need something like this? Why would you want to go through the extra trouble of logging in each time with this additional information? For security purposes. Because if you don’t use MFA, you are making it much easier for someone to access your account and either pretend to be you, or even worse, have access to critical banking accounts.

Some of the websites that support MFA include:

  • LinkedIn
  • Facebook
  • Twitter
  • Gmail
  • Office 365
  • Dropbox
  • Flickr
  • Paypal
  • Amazon

This gives you a pretty good idea of the different types of sites that support MFA, and there are many more that do.

To set up MFA, just go to the website and search for multi-factor authentication or two-factor authentication and then follow the setup guide. It’s generally pretty easy to set up MFA. Once you’ve set it up, please make sure to test it from a different device to make sure you understand how to log in to the site.

Multi-Factor Authentication systems are not the end all be all for your security. There are ways for hackers to defeat this type of authentication system, but what it does is make it much harder for people to access your accounts. You should also be changing your passwords on a regular basis. And please, please do NOT use the same passwords on multiple sites! Use a password manager like LastPass to keep track of your passwords and use it to generate strong passwords. The longer the password, the better. So, instead of 7 or 8 characters, aim for 15 characters or longer.
