What is MFA? Why is it important?
What is MFA? Why is it important? What is MFA? MFA is an acronym for Multi-Factor Authentication. It is the term people in the IT world use to describe the process of a computer checking your identity in more than one way before it lets you into your account. The terms are however important to understand, as they help you to better understand how MFA works and why it’s important. A deeper look at what MFA means You might be sitting there thinking that you know exactly what ‘multi-factor’ means. You could well be right, so let’s skip defining what ‘multi’ means. Just to be thorough, and because we are going to talk about factors in a bit more detail, let’s take a look at what ‘factor’ means in IT semantics. A ‘factor’, in the context of authentication, is a way of defining your identity. The password you type into an account to log-in is one factor through which a computer confirms you are you. It is the most common factor used. Confirmation of the password grants you access into your account. The computer has authenticated your identity through the combination of your username and password matching. This is the ‘authentication’ process. With MFA, you use more than one factor to confirm your identity alongside your username. MFA uses a combination of three factors to confirm your identity, all of which are interlinked and about you, so you will know them. Three factors By using all or a combination of options from these three different key factors, MFA provides a more robust protection system for your data. 1: Know This is the password, pin, security question or other form of identification that you are most likely already familiar with and using to access your online accounts. If you want to manage this and save some brain space, we recommend using a password manager to keep your passwords safe. 2: Have This is something that is in your possession and that you directly link to your online account. It will most likely be the device that you log-in on or something that you are given by a business to use as part of a multi-factor authentication process. 3: Are This is you, something that physically defines who you are. This includes a fingerprint, retinal scan or facial recognition, all of which are intrinsic to you. You don’t have anything to remember and many of us are already using this form of authentication every day as part of our internal phone security. That sounds unnecessary You may now be wondering why on earth you would put yourself through the stress of trying to remember more. For every account you have using more than just a password to log-in may feel daunting. The prospect of taking more time to log-in and taking-up more brain space to remember extra steps which you worry you might forget is perhaps the reason you don’t think MFA is the best-fit for your business. If you’re thinking it isn’t for you right now, you need to read on. It is for you. MFA is necessary. It’s also really easy to do. 3 Statistics about the impact MFA 1: MFA has been found to block 99.9% of automated cyber-attacks in 2023 according to statistics. 2: Weak or stolen passwords account for 80% of cyber breaches. MFA adds layers of security to your password so one weak or stolen password will not give access to accounts. 3: 67% of customers in the UK believe that companies who use MFA care about the protection of personal data according to recent statistics. Why is MFA important? MFA plays an important role in the fight against cyber-crime for both individuals and businesses. It is an easy step you can take to protect your accounts from being easily hacked by cyber-criminals. If they have your username, which let’s be honest is often just your name or your email address, they only need to guess your password to gain access. Once in they have access to your personal data. Do you have faith that your passwords are strong enough to defend against a hacker? If the answer is maybe, read on. Did you know that cyber security experts across the world have found that in every second there are an average of 530 signs of a potential cyber-attack? That’s a whopping 46 million indicators of potential cyber-attacks in just one day. Protecting yourself and your business from the ticking clock with MFA is usually free. It is normally something you can turn-on in the settings of your online accounts. No extra cost to you or your business. It’s just a choice you need to make. Then an action you need to implement. Take a look at the following statistics which demonstrate an interesting parallel between businesses and cyber-attacks. 2 statistics you should not ignore: 1: Over 68% of people surveyed did not use MFA where it is available. 2: Half of business surveyed by the UK government in 2024 have experienced some form of cyber-attack in the last year. It is interesting to look at these statistics and consider what impact there may be on the second statistic of people began using MFA as part of their cyber security policy. How does MFA work? To describe how MFA works and why you should use it, let’s use an analogy. Your password is the lock you use on your door to gain entry to your house – the place you keep all the information that belongs to you and that you are responsible for looking after. Using one password is like having one lock. If your password isn’t very strong, it’s like using a padlock on the front door to your house and hoping you won’t get robbed. The weaker the password; the flimsier the padlock. If you’re using the word password for your password, you’ve forgot the lock entirely. The chances of a thief gaining access to your home and robbing you is high.
