iOS 11 already has a feature that lets you share your Wi-Fi network’s password with your friends without actually revealing the passcode. But even to use that feature, you have to manually authorize it each time and there’s a bit of song and dance process involved to get it working just right. What if you want your friends to connect to your Wi-Fi network securely, without the need for a password and where they don’t bug you about it? Simple, get a QR Code.
