Find out the Wi-Fi password connected to your MacBook (Apple laptop)
First, you have to open the Finder application, then choose the Applications section from the left side of the program, then open the Utilities folder from the program window.
Now run the KeyChain Access.app which has an icon that looks like a chain of keys.
Select the System section under Keychains and make sure that you have selected Passwords under the Category section. Now select your router from the list and double-click on it.
From the window that will appear, select the Show Password option at the end of the window as shown in the picture.
In this way, you will have known the password of the Wi-Fi network you are connected to without programs on the MacBook. Keep in mind that you may be required to enter the username and password for it to show you the Wi-Fi password.
