How to Make a WiFi QR Code
A WiFi QR code encodes the network name, security type, and password so a phone joins with one scan. It is the single most useful code for cafés, rentals, waiting rooms, and home guests. You can do all of this free at liveqr.codes — no signup needed for a static code, and a one-time $1.99 upgrade unlocks unlimited dynamic codes with scan analytics.
Steps
- Collect the exact network details — Write down the SSID exactly as broadcast, including capitalisation and spaces, plus the password and the encryption type (usually WPA/WPA2).
- Use your guest network when possible — Encoding a guest network keeps visitors off the devices, printers, and cameras on your main network.
- Fill in the WiFi fields — Enter SSID, password, and security type in the WiFi QR generator. Tick the hidden-network option only if the SSID is not broadcast.
- Test on both iOS and Android — iPhones show a "Join network" banner, Android shows a connect dialog. Test both because a wrong security type fails silently on one platform.
- Print and display it — Print at least 4 x 4 cm and place it at eye level near where guests sit. Add the network name in text underneath as a fallback.
Pro tips
- Change the password and regenerate the code periodically
- Laminate codes used in kitchens or bathrooms
- Special characters in passwords are supported but must be typed exactly
Frequently asked questions
Is a WiFi QR code safe?
Anyone who scans it can join the network, so use a guest network and treat the printed code like a written password.
Does a WiFi QR code work on iPhone?
Yes. iOS 11 and later reads WiFi QR codes with the built-in camera app and offers to join the network.
Can I use a WiFi QR code for a hidden network?
Yes, enable the hidden flag when generating so the phone knows to search for the SSID instead of expecting a broadcast.
