How to make a Wi-Fi QR code
A Wi-Fi QR code holds your network name and password in the format phones understand. When a guest points their camera at it, the phone offers to join the network. They tap once and they are online, with no spelling out a long password across the counter.
- Type the network name (SSID) exactly as it shows in the Wi-Fi list, with the same capital letters
- Pick the security: WPA, WPA2 and WPA3 share one option, WEP is for old routers, and None is for an open network
- Type the password; the eye button lets you check it
- Tick Hidden network only if your network does not appear in the list
The text shown under the preview keeps the password as dots while the box is hidden, so people looking at your screen do not see it. The code itself still holds the real password.
Share your Wi-Fi password with a QR code at a cafe or restaurant
Cafes, restaurants, salons, clinics, guest houses and offices print this code so staff are not asked for the password all day. Put it on table tents, on the menu card, near the cash counter or on the waiting room wall. At home it is handy on the fridge or near the TV for visiting family.
The default label says Join our Wi-Fi, and you can change it, for example to Free Wi-Fi for customers. A card frame in your brand colour makes the code easy to spot on a busy wall.
Use a guest network, not your main one
Anyone who scans the code, or takes a photo of it, can join. Most routers let you create a separate guest network. Make the code for that network so your main devices stay apart from visitors. If you change the router password later, the old printed code stops working and you will need to make a new one.
Printing tips for a Wi-Fi password QR
On a table card, about 4 to 5 cm wide is enough for a phone held close. On a wall that people scan from a step away, go bigger. Download the large 2048 px size for print and keep dark dots on a light background. A long password makes the code denser, so do not print it too small.
Laminate the card or put it in a clear stand so it survives spilled tea and cleaning. Matte lamination is better than gloss, because shiny surfaces throw light back at the camera. Write the network name in small text under the code too, so guests can find it in the list if their phone is old.
Wi-Fi QR code not connecting? Check these
- The network name must match exactly, including spaces and capitals
- The security type must match the router; most modern routers use WPA2 or WPA3
- If you set Security to None, the network must really be open
- If a phone joins but shows no internet, the problem is the connection, not the code
Special characters like semicolons or colons in the name or password are fine; they are handled for you when the code is made.
