I find it a bit frustrating when I forget a WIFI key for a particular access point. I find it even more frustrating having to find out by going to system settings or worse, asking for the key again and again. So I thought I should find a much more reliable solution to this problem. The solution, as is the case with most problems, is going to the heart of the matter: the glorious CLI.
On windows, finding out saved WIFI keys is a simple matter of typing in one command in your terminal. Fire it up by holding the
[windows key] +
[R Key] and then typing cmd.
netsh wlan show profile name=[SSID] key=clear #[SSID] is a placehoder for the name of the access point
On linux, fire up your terminal and read from the System Connections directory.
sudo cat /etc/NetworkManager/system-connections/[SSID] | grep psk= #[SSID] is a placeholder once again
security find-generic password -wa [SSID] #[SSID] is...Oh you catch the drift
And there you go.
