How to Create a QR Code that Connects Devices Automatically to the WiFi

6 minutes ago read

Connecting to wifi automatically with a QR code is a process that allows users to connect to a wifi network by simply scanning a QR code with their smartphone, instead of manually entering the network's name and password. Here's how it works:

Generate a QR code for the wifi network. 

A QR code can be generated using The QR code contains the wifi network's name (SSID) and password encoded within it.

Display the QR code. 

The QR code can be displayed on the screen of the wifi router or access point, or it can be printed and placed in a visible location.

Scan the QR code. 

When a user wants to connect to the wifi network, they simply open their smartphone's camera app and scan the QR code. Some smartphones have the ability to connect automatically when a QR code is scanned, on others you might need to install a QR code reader app.

Connect to the wifi network. 

Once the QR code is scanned, the wifi network's name and password are automatically entered into the user's smartphone's wifi settings, and the phone will attempt to connect to the wifi network. If the connection is successful, the user will now be connected to the wifi network and can start using the internet.

This process eliminates the need for users to manually enter the wifi network's name and password, making it a more convenient and user-friendly option. Additionally, it also increases security as the QR code can be generated to expire after a certain time or a certain number of scans, making it less likely that someone else will be able to connect to the network using the same QR code.
