Have you ever connected to so many WiFi networks, and forgot the password for one of them? 

If you have, then you're in luck! 

The WiFi Password Key Show app can help you to recover all the passwords from your system database.

It works on all the latest Android devices, including those that have an OS of 5.0 or higher.

It's free, simple to use, and requires no special root permissions.

How to use the app

After installing the app, you need to enable the "root" option in the settings.

Then you need to open it and select the "Show databases" option.

It will then list all the databases on your device.

You can now choose one of them to view the password.

When you're done, you can save it or share it with your friends.
