I am almost sure that installing a XFCE desktop also installs NetworkManager to handle connections. NetwokManager runs as a system service, uses wpasupplicant to connect to WiFi, and offers a sytem tray applet (nm-applet), a GUI (nm- connection-editor), a CLI (nmcli) and a TUI (Text User Interface - nmtui). Networks' configurations, including WiFi password, are stored in /etc/NetworkManager/system-connections/<config name or SSID>, and are readable by root. Regards, Yvan
