If you’re looking up a Wi-Fi network password, you’ll have to use a command prompt
Open the command prompt.
Then, type the following command:
netsh wlan show profile
This command will list every Wi-Fi profile that you’ve ever connected to. To reveal the password of a specific network, type the following command, substituting “NETWORK NAME” with the Wi-Fi network you’re looking up:
netsh wlan show profile “NETWORK NAME” key=clear
You’ll see your Wi-Fi password in ‘key content,’ under security settings.
