Teach you how to view the WiFi password connected to the Mac

Some friends come to the home to play, want to even the home WiFi, but they do not remember the WiFi password, how to do? On 192.168.1.1? To land, too troublesome, what else can do? Here's a simple way to teach you.

First, open the application---utility, find "Keychain access" (if you can't find it, search with Spotlight), and when you open it, you'll see something like that in the picture.

Then, search your WiFi name in the search box, and you'll probably see two identical things.

Finally, casually on a wifi point right----copy to the Clipboard, enter the administrator password, create a new text, paste it up, you see the password ~
