Retrieving your credentials
The connection details (IP address, username, initial password) are emailed when the VPS is activated, and stay available in the service detail in your client area.
Connecting from macOS or Linux
The terminal has a built-in SSH client. From a terminal, the connection command is:
ssh root@your-vps-ip
Accept the server fingerprint on first connection (shown only once), then enter the supplied password.
Connecting from Windows
Windows now includes a native SSH client usable directly from PowerShell or the command prompt, with exactly the same syntax as above. A graphical client such as PuTTY remains an alternative if you prefer a dedicated interface: enter the IP address, port 22 by default, and start the connection.
Moving to SSH key authentication
Generate a key pair on your machine if you don't already have one:
ssh-keygen -t ed25519
Then copy the public key to the VPS:
ssh-copy-id root@your-vps-ip
