If you have a complicated WiFi password, it can be a hassle trying to share the connection with visitors or connecting new devices to the network.
However, a simple solution for smartphones is sharing the WiFi connection as a QR code. This allows people with smartphones and tablets to scan the code with their device’s camera to connect, instead of having to type in the password. To share WiFi as a QR code on Android 10 devices:
1. Go to your network settings
2. Select your WiFi network
You will see the QR code in the network information. The other user will then need to scan this to connect.
