I think every network technician has been in a situation where he or she needs to recover the password from his or her laptop or desktop, often in situations where there's no time to lose. In this video, I show you how to retrieve a wireless password that is already configured in your Windows computer.
As I note in the video, this demo does not show you how to "crack" or figure out the wireless password for an unknown wireless network.
On several occasions, I've worked with someone who was using a new laptop, but didn’t remember the WPA2 password from his or her previous laptop. I showed them this nifty trick -- or I guess the kids are calling it a ‘hack’ -- to retrieve their password from the other computer.
To recap the commands I used in the video:
netsh wlan show profile
Displays all your profiles, or previously configured SSID and passwords
netsh wlan show profile name=galaxys2
Displays details of a previously configured SSID or profile called galaxys2
netsh wlan show profile name=galaxys2 key=clear
Displays the same information as the previous command, but adds the WPA2 password. Specifically, you'll find it under the Security Settings, to the right of Key Content.
For this demo, I used Windows 8, but this method also works with Windows 7 and should work with Windows 10.
Hope this helps you out. Or use this tip to help someone else who's in a bind.
