What is Two-Factor Authentication?

If you’ve been paying attention to cyber security at all over the past few years, you might have heard about two-factor or multi-factor authentication. So what is it, and how does it apply to text messaging?

Two-factor or multi-factor authentication is when a person selects a service (email, phone call, text message, or third-party application) that they will use to verify login attempts for their various accounts. The most common form of two-factor authentication is a text message, where a given short code number will text the user a confirmation code that they can use to verify their login. This process is repeated with every new login attempt, with a fresh code sent to the phone each time.

You can see an example of two-factor authentication below.
