How do I make a QR code for my Wi-Fi?
Choose the Wi-Fi type, enter your network name and password, and select the security type. The code appears instantly. Guests scan it with their phone camera and are offered to join the network.
Wi-Fi QR code generator
Share your Wi-Fi without ever spelling out the password.
Your text never leaves this device.
Enter your network name, password and security type, and the generator builds a QR code that phones read as a Wi-Fi login. Guests scan it with the camera and join without typing. Hidden networks are supported. Your password is encoded in the code on your device and is never uploaded anywhere.
How to use
- Choose the Wi-Fi type and enter the exact network name (SSID).
- Type the password and pick the security type, usually WPA.
- Tick the hidden network box only if your network does not broadcast its name.
- Download a PNG or SVG, print it and test it with a phone.
Frequently asked questions
Which security type should I choose?
Choose WPA / WPA2 / WPA3 for almost every home and office router. Pick WEP only for very old equipment, and the open option only if the network has no password at all.
Does the QR code work for hidden networks?
Yes. Tick the hidden network box so the phone knows to connect to a network that does not broadcast its name. Without it, the phone may not find the network.
Can people see my Wi-Fi password in the QR code?
Yes, anyone who can scan the code can also read the password, because it is stored in the pattern as plain text. Share it only where you would be happy to share the password itself.
What happens if I change my Wi-Fi password?
The old QR code stops working for new connections, because it still contains the old password. Generate a new code and replace the printed one.
Do I need an app to scan a Wi-Fi QR code?
No. The camera app on current iPhones and Android phones can read it and offer to join the network. Older phones may need a separate scanner app.
Why does my Wi-Fi code not connect?
The usual reason is a typo: the network name and password are case-sensitive, and special characters must match exactly. Check both, confirm the security type and generate the code again.
Is it safe to type my Wi-Fi password into a website?
Here, yes: the code is built in your browser and the password is not sent to a server. Still, treat the printed code like a written password and keep it out of public view.
Where should I put a Wi-Fi QR code?
The best places are the ones where guests ask for the password again and again: a living-room frame, a guest room, a rental apartment, a cafe counter or a meeting room. A small framed card near the place people sit saves you from reciting a long password to every visitor.
Because the code carries the password in readable form, think about who can reach it. In a private home that is fine. In a public cafe, put it on the counter rather than on the street-facing window, or create a separate guest network that you can reset easily.
Which details must be exactly right?
Three details cause nearly every failure. First, the network name must match the router exactly, including capital letters and spaces. Second, the password is case-sensitive and a lowercase L and a capital I look alike, so copy it from the router settings rather than retyping it from memory. Third, the security type must match what the router uses; if you are unsure, WPA is the safe default for modern routers.
If your router broadcasts two names for the 2.4 GHz and 5 GHz bands, you can make a code for either one. Choose the one guests are meant to use and label it clearly.
How do I print and keep it working?
Print the code at least 3 to 4 cm wide with a light border around it, and test it with an iPhone and an Android phone before you frame it. Dark on light always scans best. A small logo can make the card friendlier, but it forces the highest error correction and makes the pattern denser; see QR code with logo before you add one.
Write the network name in plain text under the code, so a guest whose phone cannot scan can still join by hand. And whenever you change the password, print a new code on the same day and throw the old one away.
What other codes help a host or a business?
If you also want visitors to open your menu or house guide, make a link code with the main QR code generator. To hand over contact details instead, use a vCard QR code. And if a guest sends you a photo of a Wi-Fi code, the QR code scanner can read what is inside it.
How it compares
| This tool | Upload-based services | |
|---|---|---|
| Is your text sent to a server? | No | Usually |
| Account required | No | Sometimes |
| Length or usage limit | None | Often |
| Saved or logged | Never | Possibly |
Limits and privacy
- The password is readable by anyone who scans the code, so do not put it on a poster in a public place.
- Changing the Wi-Fi password makes printed codes useless, and they cannot be edited.
- Enterprise networks with a username and certificate (WPA-Enterprise) are not supported; the code covers password-only and open networks.

Use it in your AI assistant
To create a Wi-Fi code from your assistant, connect the QR MCP server and ask for the generate_qr tool with the Wi-Fi type, for example “make a Wi-Fi QR code for the network Guest with password sunflower42”. It returns a real PNG and SVG.
