What is Two-Factor Authentication?


Two-Factor Authentication (2FA) is a very secure way to protect your online accounts. It works by requiring you to identify yourself using two different methods when you log into your account. The second factor is linked to something "you have" (such as a cell phone). So you can think of Two Factors as something you know (your password) + something only you have (your cell phone).
