How to find the Wi-Fi network password (and other settings) via command line in Ubuntu
February 7, 2018 Comments
While you can get this information via the "Network Connections" GUI, it could come in handy sometimes to know where this is located. For example, you might want to write a script to display the SSID and passwords of all the Wi-Fi networks you've connected to.
Basically, all the network connections are saved under /etc/NetworkManager/system-connections in Ubuntu in separate configuration files. If you want to delete all the Wi-Fi settings in bulk (for privacy reasons or if you're having some weird connection issues), you can also just quickly delete them from here.
To see the Wi-Fi password and other settings for the network you're connected to, just do:
sudo cat /etc/NetworkManager/system-connections/THE_SSID_OF_THE_WIFI
