Finder>Utilities>Key chain. Open it. It should be in Keychain Access. Select the "login" keychain in the "Keychains" list, then "Passwords" in the "Category" list. Then scroll through the list to find it. Can't remember, but if you don't see the password there should be a little i you can click on that will expose it.
