Things to know before starting the explanations: 
This tip is not NOT a literal hack of a router's wifi codes. But it still allows you to do something interesting!

What is it for?
Have you ever been at a friend's house, or in a public place or even your high school or workplace and had access to a computer that is connected to a wifi network? This wifi network is secure and you can pick it up with your smartphone, tablet (Android or IOS) or even your laptop. Unfortunately, the latter is secured by a password... like almost all wifi networks. Well, simply by having access to this PC which is connected to this network, you will be able to retrieve the wifi code(s) to be able to connect to it with your device!

How does it work?
When a computer connects to a wifi network, the password of the latter is saved in the PC so that it remembers it and connects you to it whenever you want without having to retype it each time. There is therefore a way to find and display these codes very simply without even needing software. We will therefore use the command prompt (CMD) and with only two lines of code we can see which networks the PC has connected to. Then we can see the code of the network that interests us later. Know that a network is generally not forgotten, for my part as you can see in the video the public networks (orange for example) are still visible even though I connected to it 2 years ago during an internet outage. As said, this is therefore not a hack but simply a display of the codes saved on a PC.
