I've been in situations where I often forget my Wi-Fi password as it consists of complex characters and symbols i don't typically use.
I recently learned of a way to figure out the wifi password if you happen to have a device connected already and just don't remember it.
If you type "netsh wlan show profile
WIFISSID key=clear" in your command prompt <- replace the
WIFISSID with your Wifi name. It should spit out the wifi password key that is being used.
Note: This does not require admin rights!
Here's a screenshot of me figuring out my forgotten wifi password. Hope this helps anyone!
