CadetNet MFA Registration
CadetNet MFA
Pre-register
The CadetNet Modernisation project will deliver a new online collaboration platform through Microsoft 365. With this new digital platform there will be new ways of working - one of those changes is in how you will access the applications.
Introducing Multifactor Authentication
Multifactor Authentication (MFA) keeps your personal information and accounts secure. It also protects Defence’s applications and systems against threats.
Pre-registration for MFA
All CadetNet users are encouraged to preregister for MFA. You will not be able to gain early access to M365 but it will help to start the process before the new go live on Tuesday 21st October 2025. You can pre-register by following the steps in the Help Guide here.
How can I set up MFA?
There are multiple ways that you can set up MFA but the best way is to download the Microsoft Authenticator application on your smart device, or a smart phone that you can access.
This is the best way to receive the authentication code and you can access our Help Guide here for more information on how to set up a Microsoft authenticator account. It is also a good idea to turn on MFA wherever it is available to protect all of your accounts!
What is MFA?
MFA is a two-step process to prove that you are who you say you are. This is called authentication and once you enter your username and password, you will be required to authenticate by using a unique code as the second step.
There is a good chance you are already using MFA. It is very common and is used to access work and school accounts, and to also unlock accounts for banks, Google, Facebook, streaming services, online interactive games and more.
Why do we have to use MFA?
Usernames and passwords are information that can be easily discovered and used to take over not just your CadetNet account but also other personal or work accounts if you have repeated the same password.
Having an extra step can be inconvenient at first, but remember that taking shortcuts leaves your system more vulnerable to avoid spending hours later on trying to regain access to your accounts and dealing with the consequences of your data being stolen.
How does this change the way I access CadetNet?
The look and feel of the log on screen that you are used to seeing will be changing so that we can activate MFA. As well as entering your username and password, MFA will require a second step to authenticate who you are. To do this Defence will be using the Microsoft authentication process
What if I don’t own or have access to a smartphone?
Defence is working on a solution to support you. In the meantime, you can download an authentication application to a tablet, laptop or PC that you own or can readily access when you need to use CadetNet. This application will provide you with the code you need to authenticate, however you will need to make sure your device is kept secure.
If this doesn’t work for you talk to your unit command to obtain printed versions of activity schedules, communication notifications, forms, and training material. Support will be considered on a case by case basis.
