Multi-Factor Authentication (MFA) Or 2 Factor Authentication(2FA)
What is MFA or 2FA? This basically means you need more than one credential to log on to your IT resources for example, your systems, files, networks, online accounts such as banking or email or on to a secure website, it is used to keep you and your business secure and this works by using or leveraging:
• Something that you know – like your username and password
• Something that you have – like a code sent to your smart phone
• Something you are – like a fingerprint or iris scan
Why do we use this method? Well hackers can easily crack a password but obtaining your phone and using the Multifactor token or code that was sent to your phone at the same time can be very challenging. Therefore, implementing MFA or 2FA within your organisation can be such a vital tool in securing your IT infrastructure. The difference between MFA and 2FA is that MFA uses more than 2 methods of authentication. So for example when logging on to your bank account online, it will require you to enter your username and password (something that you know), then it will send a token or code to your smart phone to enter (something that you have) and lastly it might require you to enter a another form of authentication like your fingerprint on your phone (something you are), while 2FA will just require to bits of authentication.
Businesses or people that use some sort of MFA are more secure than those who don’t, this is a big deterrent for hackers as it makes life for hackers incredibly harder to hack your account if there are multiple forms of authentication in place. Whenever you can utilise a system like MFA, you should be using it.
