Quickest way to find saved wifi passwords in a mac machine (within 30 seconds)

I recently borrowed a friend’s MacBook Air laptop, and he challenged me to find a certain wifi password that was already connected to the laptop in past without threatening him 😂 or scanning the QR code for that wifi, etc... I’ve found the quickest and simplest way to accomplish this after doing some study on this. Here is the solution :

Press the following keys to launch Spotlight Search. Type “terminal” into the search box and hit Enter.

command + spacebar

Now the terminal will be displayed, it will look like this.

Now type the following command and hit Enter.

security find-generic-password -wa "wifi_name"

Replace wifi_name with the name of the wifi network for which you’re looking for the password. (type the wifi name within double quotes)
The following prompt will appear if the laptop has access to that wifi’s data.

In order to complete the command successfully, I needed the admin username and password at this point (If you are familiar with them, enter them right away).
TADA !! Now you will have the wifi password in your terminal window.
