How to easily share Wi-Fi networks using QR code

It is very important that one uses a strong Wi-Fi password for their home or office network which is a mix of alphabets and numbers. However, a complex password can become a headache when you have guests over at your place and they want to use your Wi-Fi network. This does not mean you should use a weak Wi-Fi password to avoid such situations though. In other cases, there is a possibility that your device is connected to a Wi-Fi network whose password you don't remember or have access to but would want your friends or family to join it. For such situations, Android 10 introduces a handy option of sharing a Wi-Fi network using QR codes. This QR code can then be scanned by any smartphone to join the Wi-Fi network.
