Remembering the WiFi password when on a guest network is never easy. Even worse is when it’s no longer posted and someone else is asking you for it. Luckily there’s a built in Windows command to recover the password of a given WiFi network.
The Shell Code
Open cmd and execute the following command:
netsh wlan show profile name="David Walsh's Network" key=clear
The result of the command, assuming the network is found, is a long text output with a variety of information about the network. To get the see the password for the network, look under the “Security settings” heading which will look like this:
Security settings
-----------------
Authentication : WPA2-Personal
Cipher : CCMP
Authentication : WPA2-Personal
Cipher : GCMP
Security key : Present
Key Content : **THE_PLAIN_TEXT_PASSWORD**
As with any complicated command line format, it’s best to create an alias so that you don’t need to remember the full string!
