This app requires root access to run. An optional Xposed module is included.

Ever wanted to easily give a friend access to your wifi?
Ever wanted to see a saved wifi password?
Ever wanted to check a network's security type?

If any of the answers to those questions is "yes" then this is the app for you.
Wifi QR Code Creator and Info lets you easily share your wifi networks as QR codes. All anyone who wants to connect to your wifi just has to scan the generated QR code and press connect¹.

As well as creating QR codes this app also shows information about wifi networks like the SSID password and security type.

Have the Xposed Framework? Keep reading.
The Xposed module only works on Android 6.0 and higher.
With Xposed shortcuts to show network info and create QR codes are added right in the system wifi settings. When launched from the system settings even more network information can be shown like if it's metered² saved or connected.

1. Only works on QR scanner that support wifi QR codes but don't worry I've never seen a scanner that doesn't.
2. The network shows as metered if it's been manually set to metered from the android settings or if Android detects it as metered. The network may actually be different to what is shown.
