Internet of Things (IoT) allows different devices to communicate with each other without the compulsion to use outdated-fashioned communication styles such as data cables, external flash drives, and disks. Nowadays, people connect their smartphones to Wi-Fi in the public area by manually inputting a Wi-Fi password on their smartphones, which is regarded as a problem, mainly when the password is complex and confusing. This research demonstrates the feasibility of using the Quick Response (QR) code and the Captive Portal featured in router Tenda W15E AC1200, to guard the Wi-Fi password and to avoid unwanted users from exploiting the Wi-Fi public area. Simulation by using an open source QR code generator software to acquire the Wi-Fi QR code and experimentation from both qualitative and quantitative approaches are therefore necessary. As a result, the safety of the Wi-Fi public area is protected as the password is not revealed to the user.
