### What is two-factor authentication? <a href="#what-is-two-factor-authentication" id="what-is-two-factor-authentication"></a>

Typically when we log into computer systems, whether it an email account or the MNX portal, we supply a username which identifies us and a password which authenticates us. This is "single-factor authentication" using a password, a series of characters that (hopefully) only we know.

Two-factor authentication (i.e. "2FA") seeks to improve security by adding a second type ("factor") of authentication. The first factor is still a traditional password. The most common second factor is a one-time password (OTP) generated by a physical device or by software on a smartphone.

The advantage of using a second factor of authentication is that if your password being compromised, that alone isn't sufficient information to gain access to your account.
