Wi-Fi sign
A Wi-Fi sign that answers the question before it is asked.
"What is the Wi-Fi password?" is the question almost every host gets. A printed sign with the network name, the password and a QR code that joins in one tap stops it.
Short answer
Print the network name and password in large type, plus a Wi-Fi QR code. Most current iPhones and Android phones join the network when the camera reads the code. Put the sign where guests look first, such as the fridge or the inside of the front door.
How a Wi-Fi QR code works
A Wi-Fi QR code is not a link. It holds a short piece of text in a standard format that phone cameras understand:
WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;
T is the security type (WPA for most home routers), S is the network name and P is the password. The camera app reads it and offers to join. Nothing is sent to the internet, and the code works without a website behind it.
Special characters in the name or password (; , : \ ") must be escaped with a backslash, or the code will fail. Good generators do this for you; Welcomefold does.
What to put on the sign
- The network name, exactly as it appears in the phone's Wi-Fi list.
- The password in a clear font. Avoid fonts where 0 and O, or l and 1, look the same.
- The QR code, at least 3 cm wide so it scans from a step away.
- One line of instructions: "Point your camera at the code to join."
- Optionally a second code that opens your full guest guide, with check-out times and local tips.
Where to put it
- On the fridge or a kitchen cupboard: everyone ends up in the kitchen.
- Inside the front door, at eye height.
- By the router, if guests will need to restart it.
- Framed on a shelf if you prefer it to look like decor.
Keep the sign inside the home, not on an outside door or window. Anyone who can see it can join your network.
Printing tips
- Print at 100 % scale. Shrinking to fit can make small codes hard to scan.
- Use matte paper or a matte laminating pouch. Glossy plastic reflects light into the camera.
- Test the printed code with an iPhone and an Android phone before you put it up.
- When you change the password, reprint the sign the same day.
Make the sign in Welcomefold
Type your network name and password into the guide editor, open Print, and choose an A4 poster, two A5 cards or four mini cards. The poster and cards show the Wi-Fi details and a join code, plus a code that opens your full guest guide. It is free for your first guide.
Questions hosts ask
Do guests need an app to scan a Wi-Fi QR code?
Usually not. The built-in camera on most current iPhones and Android phones recognises Wi-Fi codes. Some older phones need a QR scanner app or Google Lens.
Is it safe to print my Wi-Fi password?
It is as safe as telling guests the password, which you have to do anyway. Keep the sign inside, consider a separate guest network if your router has one, and change the password now and then.
Does the Wi-Fi QR code stop working if I change the password?
Yes. The password is inside the code itself, so you need to print a new sign. The guest guide code on a Welcomefold Pro sign stays the same, because the live link updates.
Why does my Wi-Fi QR code not work?
The most common causes are a typo in the network name (it is case-sensitive), the wrong security type, or special characters that were not escaped. Hidden networks also need an extra setting.
