Home/Sufficiently privileged users can typically get the WiFi password of an Access Point that they are currently connected to by doing the following:
- Connect to the WiFi AP you want to un-mask the password for
- Right-click the WiFi symbol in the systray and select ‘Open Network and Sharing Center’
- Click ‘Change adapter settings’
- Right click the WiFi adapter
- In the WiFi Status dialog, click ‘Wireless Properties’
- Click the Security tab and then check ‘Show Characters’ – this should show your current Wifi password
However, there are cases where this option isn’t viable – either the machine is locked down and doesn’t let you select ‘Show Characters’ – or you are in a situation where you are not in range of the WiFi AP to actually connect. Try this via the Windows command prompt (cmd.exe):
Run this command to list the wifi profiles the machine knows about:
netsh wlan show profiles
Then show the password for a specific profile:
netsh wlan show profiles name=<profile> key=clear
Replace <profile>
with your profile name / SSID.
The password should be shown in Key Content:
