One very easy and convenient way to share access to a wi-fi router is by generating a QR code for joining that wi-fi router, which can be useful for house guests, offices, waiting rooms, rentals, restaurants, shops, and just about anywhere else with wi-fi that people might want to join. It can also make it much easier for someone to join a wi-fi network without them having to enter in a long complicated password. The latest versions of system software for Mac, iPhone, and iPad, make this task easier than ever, able to generate a QR code for any connected wi-fi router that someone can easily join simply by pointing the camera at that QR code.
