wifi key finder(Root)

Wifi key finder is an app that shows you the passwords of all the WiFi networks you've ever connected to. The app doesn't hack routers, WiFi networks or anything like that; it simply displays a list of all the WiFi passwords you've ever entered using your device.

To be able to access this list, your device needs to have 'root' access. If your Android is not 'rooted,' the app probably won't work.

Wifi key finder is an app that's more useful than it may seem at first glance. No, it doesn't let you get a free Internet connection, but it does show you any WiFi password that you previously entered using your device.
