VNC lets you see the VPS display and use its keyboard even when SSH or RDP is unavailable. Open Console launches noVNC in your browser; a desktop VNC client is another option.
At the operating system’s login screen, use your Linux or Windows username and password. The separate VNC password is for desktop VNC connections; it is not your operating-system password and is not required to open the browser console.
With VNC enabled, the Information panel shows the VNC hostname, port and password. Use those values in your preferred desktop VNC client, then log in to the operating system when prompted.
Close the console or desktop client and click Stop VNC in the portal. The panel returns to VNC: DISABLED and Open Console becomes unavailable. Stopping VNC disconnects console access; it does not stop the VPS.
