Most of the time you’ll have the password for your home Wi-Fi written down somewhere, usually on the back of your router. However, what if it has been a while since you connected a new device, or no longer have it written down? You can quite easily get the password from a device already connected to the Wi-Fi network.
To do this, open the command prompt on the Windows device that is already connected. Type ‘cmd’ into the search field on the bottom left of your screen.
Type: netsh wlan show profile “<wi-fi network>” key=clear
Substitute <wi-fi network> for the name or SSID of your WiFi network. Use key=clear to ensure the password is shown in readable clear text.
You’ll see the password in the ‘security field’ in the details.
