Mac Tip: Get wifi password from another (connected) Mac

Here’s the situation: say you are at a friend’s place and as all responsible hosts, they have a password protected wifi network. Your friend is busy (or unavailable) so you can’t ask her for the password.¬†Of course, you are known to not give up easily. You look around and realize: aha! someone else over there on the couch is busy with their laptop, so they must know the password. Unfortunately, they don’t. But the password must be somewhere on their laptop, since they are connected after all. So how do you find it?

OK, that probably sounds contrived. But the truth is that I did have the need to extract the wifi password from my wife’s laptop earlier today and thought I’d share the (pretty simple) process.

Step one: open keychain access

Step two: search for the network name (SSID)

Step three: check ‘Show password’ (you may need to enter your password first since this required Administrator privileges).

Voila!
