About this Wi-Fi QR code generator
This tool turns your network name, password and security type into a QR code that phones can scan to join the network, with no typing. It is useful for guests, a rental, an office lobby or a cafe sign. The code is built in your browser with a bundled QR library. Your password is never sent anywhere, and nothing is stored once you close the page.
How to use it
- Type the exact network name. It is case sensitive.
- Pick the security type. Choose WPA for WPA, WPA2 and WPA3 networks, WEP for old WEP networks, or None for an open network with no password.
- Enter the password and tick Hidden network only if the router does not broadcast its name.
- Download the PNG or print the code. Scan it with a phone camera to test it before you put it on display.
What is inside the code
The QR code holds one line of text in the format used by the ZXing project and read by the camera apps on current iPhone and Android phones: WIFI:T:WPA;S:MyNetwork;P:MyPassword;H:true;;. T is the security type, S the network name, P the password, and H marks a hidden network. The tool adds a backslash in front of any backslash, semicolon, comma, colon or double quote in the name or password, as the format requires, so a password such as pa;ss:1 still works. The line the tool shows beside the code is exactly what was encoded.
Good to know
- Anyone who sees the code can join. A printed Wi-Fi code is the password in a different form. Put it where only people you trust will see it, or use a guest network.
- Change the password and the code is out of date. The code does not update itself. Generate and print a new one.
- WPA3-only and enterprise networks. The standard text format covers personal networks with a shared password. Networks that need a user name and certificate (WPA-Enterprise) cannot be joined from this kind of code.
- Print it large enough. A code printed at 3 cm or more with a white margin scans reliably from arm's length.
For links, text and other kinds of code, use the QR code generator. To check a printed code, the QR code scanner reads an image file in your browser.
Frequently asked questions
Enter the network name and password, choose the security type, and download the PNG. Scanning the code with a phone camera offers to join the network.
The code is generated in your browser and the password is not uploaded or stored. The code itself contains the password in readable form, though, so share the printed code only with people who may use the network.
Pick WPA for almost every home and office network, including WPA2 and WPA3. Pick WEP only for very old equipment, and None for an open network.
It adds H:true to the code so the phone knows to look for a network that does not broadcast its name. Leave it off for normal networks.
Check that the name and password match the router exactly, including capitals and spaces, and that the security type is right. Make sure the camera app, not a third-party scanner, is used; some scanner apps only show the text.
Yes. The code holds the password at the time you made it. After a change, generate a new code and replace the printed copy.
