Have you accidentally disconnected from your WiFi network and have trouble connecting back because you forgot the password? If you have, then WiFi Passwords [ROOT] is a tool you should keep on hand.

This utility app allows you to recover the passwords from WiFi networks you've connected to in the past. With this tool, you can view the password of the network you are currently connected to and share recovered ones through your social apps.

You can even sort he WiFi networks by name, priority, or security type.

Note that the app needs permission to have root access to your device, but only for the recovery process.
