Protect Your Device

What is MFA?

  • MFA stands for Multifactor-authentication and it provides an additional layer of security by adding an extra step to the login process, requiring you to confirm your identity via a mobile device.  
  • If you use mobile banking you will most likely have come across Multi-Factor Authentication already – you may need to enter your login details and then use your device to generate a code to verify your identity and give you access to your account. 
A computer login screen and a mobile phone which has a message onit prompting the user to accept or reject the login the computer.

How does it work?

  • MFA adds an additional layer of security by requiring an extra login step to validate your login. This extra step makes it significantly more difficult for an attacker to access your account, even if they manage to discover your username and password.
  • This extra login step is called your Second Factor, is usually carried out using a mobile device and can be configured in the following ways:
  • ​​​A push notification through the Microsoft Authenticator app. This is the most secure and convenient method and is recommended by Information Services. The app can also work offline by generating a 6 digit code. You can find out more about the Microsoft Authenticator app and download it on Microsoft's website.  
    A text message to your phone, containing a 6 digit code. This option is intended for those without a device capable of installing the Authenticator app.
