It’s normal to forget the password of the Wifi network you use regularly or even the one you’re currently connected to. This is mainly because your computer remembers the Wifi password for you so that you don’t have to keep logging on manually
It’s convenient but it makes you forget the password. Fortunately you can dig into your Mac and find the password of the Wifi network you’re currently connected to. You can even look up the password of any Wifi network you previously connected to with your Mac.
