Create Guest Wi-Fi With QR Code and Easy Access With Raspberry Pi
If you have a lot of guests who come and ask for a Wi-Fi password, then you know how difficult it is to give it out while keeping your network secure. DIYer NicoHood used a Raspberry Pi to enable a QR code system for easier login.
Using a Raspberry Pi and a touchscreen, the system generates a new password every day, and when someone wants to access the network, they just need to scan a QR code. The system uses a second Wi-Fi network away from its home network, so guests can access the Internet, but nothing else. You will find everything you need on GitHub.
