2-Factor Authentication

​An extra layer of security that is known as "multi factor authentication"

In today's world of increasing digital crime and internet fraud many people will be highly familiar with the importance of online security, logins, usernames and passwords but if you ask them the question "What is Two Factor Authentication?" the likelihood is they will not know what it is or how it works, even though they may use it every single day.

With standard security procedures (especially online) only requiring a simple username and password it has become increasingly easy for criminals (either in organized gangs or working alone) to gain access to a user's private data such as personal and financial details and then use that information to commit fraudulent acts, generally of a financial nature.

How does it work?

Two Factor Authentication, also known as 2FA, two step verification or TFA (as an acronym), 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.

Using a Two Factor Authentication process can help to lower the number of cases of identity theft on the Internet, as well as phishing via email, because the criminal would need more than just the users name and password details.
