Create a WiFi QR code for your guests
Share the right network, keep credentials intentional, and make a useful sign for visitors.
Use a guest network when possible
Start with a guest network configured on your router if that feature is available. The QR code contains connection details; it does not create a guest network or change the router’s access settings.
Anyone who can read or photograph the code can obtain the password from it. Display it where you are comfortable sharing those credentials, and avoid posting a private home or work network publicly.
Copy the details exactly
Enter the network name (SSID), matching spaces and capitalization. Choose WPA/WPA2 Personal for a matching personal network, legacy WEP only if your network uses it, or open network if there is no password. Enable the hidden-network option only when it matches the router.
This generator does not handle enterprise login methods, certificates, or captive-portal sign-in. If your network uses those, provide the instructions visitors need separately.
Download and try the complete connection
Download PNG for a simple sign or SVG for a print layout. Scan it using a phone and check that the phone actually joins the intended network. Support depends on the phone and its QR reader.
Label your sign with the guest network name and a short instruction such as ‘Scan to join guest WiFi.’ Leave the quiet border around the image clear. Include an alternative way to request access for visitors who cannot scan it.
Replace signs when credentials change
A static WiFi QR cannot update itself. When you rotate the password or rename the network, create a new code, test it, and replace old signs. Delete outdated digital copies to avoid reprinting the wrong version.
