Among the features that iOS 11 got is the ability to scan a router’s QR code using iPhone’s native camera. A Reddit user has now discovered that the operating system allows you to quickly and effortlessly join a Wi-Fi network by scanning a router’s QR Code inside the Camera app.
iOS 11 then puts up a notification on the device with the name of the recognized Wi-Fi network, allowing you to connect to it with a simple tap on the banner notification.
Assuming the user has generated and printed out a QR code which contains their Wi-Fi login details, such as the SSID and the password, anyone with an iOS 11 device can join their network by scanning the QR code, without having the network password revealed to them.
iOS 11 also makes it easy to share your Wi-Fi password with nearby devices. The stock Camera app on iOS 11 can also be used to scan other QR Codes with support for launching any linked app or website.
