Unlike public WiFi access points  in airports and coffee shops, work and home, private WiFi networks are protected by a passcode. To connect to these networks, you’ll have to provide the required passcode, and only then, you can gain access and browse to your heart’s content.
The same is applicable for WiFi hotspots created through the use of an Android device. As good as this password protection is, it can quickly get more tedious if the code is alphanumeric, long and complex. A QR code  may come in handy in such a situation.
