Multi-Factor Authentication - cyber protection that's virtually bullet proof

In terms of protecting access to your online files and data, often a username and a password is just not enough. Multi-Factor Authentication introduces 2 or more dimensions to unlock access and thereby ensuring only authorised people gain access.

Multi-Factor Authentication (MFA) refers to the access of online files and databases requiring combinations of:

  • Something you know (e.g. your username and a password) and/or
  • Something you have (a physical devise e.g. your mobile phone, ATM car, FOB key) and/or
  • Something you are (e.g. fingerprint, iris or face).

A couple of well-known examples include; withdrawing money from an ATM - you use something you know (your PIN) in combination with something you have (your ATM card); or doing online banking - you use something you know (your username and password) and something you own (your mobile phone which is sent an access code).

MFA can be used for all critical online access services. Using your username and password along with an authenticator app such as the Google Authenticator or Microsoft Authenticator (available on both Android and Apple), you can utilise as the most secure form of "something you have". 

All major web services support MFA including Facebook, Twitter, Microsoft 365, Google, and the list goes on. Your bank will support MFA too, but they may opt to use their own app, or text message with a code, but be aware, texting is a less secure method. 

If you, your staff, or your customers, in any way, have online access to your files and database(s), Loyal I.T. Solutions encourages you strongly consider implementing Multi-Factor Authentication.

Also, if you haven't already, we suggest that you undertake the free Cyber Security Assessment. To do this, simply complete the online form on our website.  We also recommend viewing our video on MFA here and listening to the podcast, available here, to learn more about Cyber Security.
