According to Wikipedia, Multi-factor authentication (MFA) is a method of computer access control in which a user is granted access only after successfully presenting several separate pieces of evidence to an authentication mechanism – typically at least two of the following categories: knowledge (something they know), possession (something they have), and inherence (something they are).

Two-factor authentication (also known as 2FA) is a method of confirming a user's claimed identity by utilizing a combination of two different components. Two-factor authentication is a type of multi-factor authentication.

A good example from everyday life is the withdrawing of money from a cash machine; only the correct combination of a bank card (something that the user possesses) and a PIN (personal identification number, something that the user knows) allows the transaction to be carried out.

Why is it important?

2FA adds an additional layer of security, making it that much harder for unauthorized users to access your online accounts.

How can you implement 2FA on your business accounts?

We recently started using Google Authenticator, a free security app that can protect your accounts against password theft. It's easy to set up and can be used as your two-factor authentication tools for popular applications that contain your sensitive data.

In the office we use it to add an extra layer of security to our PSA software that contains all of our client’s precious data. Not only is the set-up pretty easy, but the everyday use of it is effortless. After opening our PSA software application and entering my regular password, a second screen will prompt me to enter my Google Authenticator code. In which case I just have to get to my phone, open the Google Authenticator app and BAM! It gives me the code right away.


I thought this was pretty cool and easy enough to implement. And the misconception that a lot of people have in how much time is involved in adding extra security layers to their accounts was debunked once and for all.
