WiFi Key Recovery (needs root) is an application that can recover the password of a wireless network that you have connected to your device in the past.

To use the application, you need to root first.

The application can work with the WPA (Wifi Protected Access) protocol.

This is a free app that does not contain ads and does not need to be paid for.

This application is not intended to hack into an unknown/new network, it simply reads the password from the device itself.
