How to Protect Your Network: A Deep Dive into Wi-Fi QR Security Types

Understanding Security Protocols

When generating a Wi-Fi QR, you must select the correct security type to ensure the connection works. Here is what you need to know:

WPA/WPA2/WPA3

This is the modern standard. 99% of home and business networks use WPA. It encrypts the traffic between the device and the router, ensuring that bad actors cannot easily snoop on the connection. Always select WPA unless you are absolutely certain your legacy hardware requires something else.

WEP and None (Open)

WEP is an ancient, highly insecure protocol from the 1990s. It can be cracked in minutes by anyone with basic technical skills. You should never use WEP.

Open networks require no password. These are common in public cafes, but they offer absolutely zero encryption. While convenient, users should be cautious when transmitting sensitive data over open networks.

Which Option Should You Pick?

• WPA/WPA2/WPA3: choose this for almost every modern router. Phones work out the exact version when they connect.
• WEP: only for very old equipment. WEP can be cracked in minutes, so upgrade the router if you can.
• None: for open networks with no password, such as some café hotspots.

Share Wi-Fi Safely

• Use a guest network for visitors, so they can't reach your computers, printers or smart devices.
• Remember the code is the password. Anyone who photographs it can join, so don't post it where passers-by can see it.
• Change the password and reprint if a code has been shared too widely.
• Mind the special characters. OmniQRHub escapes characters like ; and : in network names and passwords, so the code connects correctly.

Hidden Networks

If your network does not broadcast its name, phones may still join from a QR code, but support varies. For the most reliable experience, keep the guest network visible and protect it with a strong password instead.
