WiFi QR code generator
Guests point their phone camera at the code and join your WiFi. No more spelling out a long password. The code is made in your browser, so your password is never sent anywhere.

How to make a WiFi QR code
Enter your network name
Type the network name (SSID) exactly as it appears in your phone's WiFi list. Capital letters and spaces matter.
Enter the password and security type
Most home and office networks use WPA, WPA2 or WPA3. Pick "No password" only for open guest networks.
Download and test it
Download the code, then scan it with a phone that is not already connected. If it joins, you are ready to print.
Where WiFi QR codes help
They save time anywhere people ask “what’s the WiFi?” over and over. Think of cafes, rental apartments, waiting rooms, offices, events and your own living room when friends visit.
A small sign with the code and the words “Scan to join our WiFi” works well. Put the network name under it too, for the odd guest whose phone cannot scan.
Getting the details right
The code has to match your network exactly, or the phone will fail to connect without saying why. Check these before you print:
- Network name. It is case sensitive. “CafeWifi” and “cafewifi” are different networks.
- Password. Also case sensitive. Watch for spaces at the start or end.
- Security type. If you are unsure, choose WPA. It covers WPA2 and WPA3 too, which is what nearly every router uses today.
- Hidden network. Only tick this if your network does not show up in the list of nearby networks.
Special characters such as ;, ,, : and quotes are fine. The generator escapes them so phones read them correctly.
Your password stays private
Many QR sites send what you type to their server to build the image. This one does not. The code is drawn by your own browser, and nothing you enter is uploaded or stored. You can even load the page, turn off your internet, and it will still work.
How a WiFi QR code works
A WiFi code holds a short line of text in a standard format that phone cameras recognise, for example WIFI:T:WPA;S:CafeGuest;P:secret;;. It contains the security type, the network name and the password. When the camera sees it, the phone offers to join that network. There is no website or app in between, so the code works offline and never expires.
Ideas for guest networks
- Cafes and restaurants: put the code on table cards or next to the till, together with the network name.
- Rentals and guest rooms: frame it in the welcome book or by the door, so guests never need to message you for the password.
- Offices and events: use a separate guest network and print the code on visitor badges or the reception sign.
If you change the password every so often, plan to reprint the code each time.
Questions people ask
Do WiFi QR codes work on iPhone and Android?
Yes. Recent iPhones and Android phones can read WiFi codes straight from the camera app. The phone shows a "Join network" prompt, and the guest taps it.
Is it safe to put my WiFi password in a QR code?
The code contains your password, so anyone who scans it can join. That is the point, but it means you should only display it where you would happily tell people the password. A separate guest network is a good idea.
What happens if I change my WiFi password?
The old code stops working, because the password is stored inside it. Make a new code with the new password and replace the printed one.
Does the code expire?
No. It is a static code. It keeps working until you change your network name or password.
Where do I find my WiFi password?
Look on the sticker on the back or bottom of your router, often labelled "WiFi key" or "WPA key". If you changed it, a computer that is already connected can show it in its saved network settings.
Does it work with WPA3?
Yes. Choose WPA. Phones use the same setting for WPA, WPA2 and WPA3 networks and work out the exact version when they connect.
Can I make a code for a hidden network?
Yes. Tick "Hidden network". The phone then knows to look for a network that does not appear in the list.
