Find Wi-Fi passwords on your Windows 10 PC
Right-click the network icon on the toolbar and select “open network and sharing center.”
In the resulting window, click “Change adapter settings,”
right-click on the Wi-Fi network,
and select “status” on the drop-down menu.
In the resulting pop-up window, select “Wireless Properties,”
then click on the Security tab.
You should see a check box beside “show characters.” Check this box to reveal your password.
(Note: Windows 10 refers to this as a network security key instead of a password.)

If you’re looking up a Wi-Fi network that is out of range, you’ll have to use a command prompt,
which is easier than it sounds:[ Further reading: Our best Windows 10 tricks, tips and tweaks ]
Open command prompt, and run it as an administrator.
Then, type the following command:
netsh wlan show profile
This command will list every Wi-Fi profile that you’ve ever connected to.
To reveal the password of a specific network, type the following command, substituting “NETWORK NAME” with the Wi-Fi network you’re looking up:
netsh wlan show profile “NETWORK NAME” key=clear
You’ll see your Wi-Fi password in ‘key content,’ under security settings.
