Command for Windows Based

Check Wireless Password

The following steps will allow you to view the security key of all your network connections, regardless of their current status (active or inactive):

Steps:
01.- Run CMD as Administrator

02.- List your WLAN profiles.
Type:
NETSH WLAN SHOW PROFILES

03.- Inspect your desired profile.
Type (yes! it's very similar to step2):
NETSH WLAN SHOW PROFILES NAME="profile_name_from_step2" KEY=CLEAR

04.- Under "Security Settings", the key will be displayed beside "Key Content"

Final remark: in case you're curious, the KEY parameter in step3, MUST BE set equal to CLEAR for the Security Key to be displayed in "CLEAR" TEXT ;-)
