Using Keychain Access in Mac Sierra
Keychain Access window is showed as following image:
By using group, category, search or short function in this window, you can browse all stored item or get exactly the one what you want.
In my case, I connected to the Wifi network named Owen so I enter “owen” in the search box. The list will be shortened and you simply double click on the item that you want to see saved password. One small editor box will appear to show more detail stored info.
In this box, click to stick “Show password” option at the corner. For the first time, Keychain Access will ask you the administrator user name and password before showing saved password. It is easy because you are the administrator, just enter it in the boxes.
Finally, the password is showed (see following figure)
Do similarly with other saved item in the list. Keychain store all your login info allowed by you before in the hard disk and in the iCloud as well.
Enjoy your Mac.
