You can prepare the SSH client on a Windows host.

To connect to the system, the SSH client requires a user login name and an SSH password (or if you require command-line access without entering a password, the key pair). Authenticate to the system using a management user name and password. When using an SSH client to access a system, you must use your user name and password. The system uses the password (and if not a password, the SSH key pair) to authorize the user accessing the system.
