Locating A WiFi Network Password Within OS X That Has Been Saved On My Mac? Is it possible to locate a wifi network password in OS X of a wifi hotspot that I may have used in the past (AFAIK wifi networks are saved), in the rare situation that I may need to see it (to share it for example) ?
If you have saved it previously, open Keychain Access (located in /Applications/Utilities or via Spotlight) and search for the wifi network name.

If you have found it, check the lowest checkbox to reveal the password. You need your login password to do so.
