What Is Two Factor Authentication

Two Factor Authentication is also known as 2FA, two step verification or TFA (as an acronym). It is an extra layer of security that is known as “multi factor authentication” that requires not only a password and username but also something that only, and only, that user has on them, i.e. a piece of information only they should know or have immediately to hand – such as a physical token.

Using a username and password together with a piece of information that only the user knows makes it harder for potential intruders to gain access and steal that person’s personal data or identity.

Historically, two-factor authentication is not a new concept but its use has become far more prevalent with the digital age we now live in. As recently as February 2011 Google announced two factor authentication, online for their users, followed by MSN and Yahoo.
