Our secure servers do not use passwords, before you can connect for the first time you will need to create an SSH key pair. You'll need an SSH generator on your Windows machine, this guide users ssh-keygen, which is built into Windows 10.
- Launch a command Prompt window (click start, type 'cmd', press enter)
- Enter 'ssh-keygen -t rsa -b 2048'
- Enter a name for the file, perhaps the name of your server but it can be anything
