A free app for Android, by Mahmoud Elserafi.
WiFi QR password Scanner is a utility that allows you to easily scan and save the QR codes you see on the Internet to your device. This way, you don't have to remember the URL or even the username, and you can just scan the QR code and save it to your phone.
The app can save the codes to your device's gallery, and you can easily share them with your friends and family. It's very easy to use, so even if you're a beginner, you can easily learn how to use it.
The app can also help you to find the password of the connected network you want to connect to. This is not a hacking app, so it cannot hack the passwords. This is a tool that will only show you the password of the connected network.
