Yes, you can create a Wi-Fi QR code for a hidden network. When generating the QR code, you’ll need to include your hidden SSID and password, just like you would for a regular network. However, you must ensure that the device scanning the code knows that the network is hidden, as hidden networks won’t appear in the list of available networks.
Users connecting via the QR code will need to manually select the hidden network option in their Wi-Fi settings and input the SSID as part of the configuration process. This can be a bit more cumbersome, but it is entirely possible.
Are there any risks to using a Wi-Fi QR code?
Using a Wi-Fi QR code generally carries minimal risks, but it primarily depends on who has access to the code. If your QR code is publicly displayed or widely shared, anyone able to scan it will gain access to your Wi-Fi network. This could lead to unauthorized access, slow performance, or even potential security risks if malicious users connect.
To mitigate risks, ensure that you’re only sharing the QR code with trusted individuals or in secure environments. Additionally, consider using a guest network to isolate visitors from your primary network, enhancing security for your personal or sensitive devices.
