Generating a QR code for joining a Wi-Fi router is a convenient way to share access to Wi-Fi networks.
The latest versions of Apple's system software for Mac, iPhone, and iPad allow users to easily generate a QR code for any connected Wi-Fi network.
The QR code can be scanned by other devices to instantly join the network without the need for entering a password.
This feature is particularly useful for sharing Wi-Fi networks with devices that are incompatible with Apple's password sharing feature, such as Android phones or Windows PCs.
