Following up on the previous post, it might be practical to find saved password on a Windows 10 device as well for similar reasons.
Note: This may require administrator access.
- Open elevated command prompt.
To list the name of all saved Wi-Fi profiles:
netsh wlan show profiles
To show the password for the specific profile you are looking for:
netsh wlan show profiles name=<NAME> key=clear
<NAME>with the name of the network shown in the step above
The PSK you are looking for is available in the section Security Settings in the field Security Key.
