Wi-Fi QR Code Generator
Let guests join your network by scanning, with no password to type.
Wi-Fi QR Code Generator: the generator
Make a QR code that connects a phone to your Wi-Fi network. Guests point the camera at it, tap the banner and are online, with no password to read out or type. Works for home, cafés, offices and rentals, and your password never leaves this page.
How it works
The code stores your network details in a format that phones understand: WIFI:T:WPA;S:name;P:password;;. T is the security type, S the network name and P the password. Add H:true and the phone knows the network does not broadcast its name. The generator writes this text for you.
Names and passwords may contain characters that the format uses as separators: a backslash, semicolon, comma, colon or quotation mark. The generator puts a backslash in front of each one, so a password like a,b;c is stored in a way the phone reads back exactly.
iPhones and iPads running iOS 11 or later join from the Camera app. Recent Android phones read it with the camera app, Google Lens or the QR option in Wi-Fi settings. Choose WPA for WPA2 and WPA3 networks, which covers nearly every home and office router.
How to use it
- Type the network name exactly as it shows on your devices, including capital letters and spaces.
- Choose the security: WPA for most networks, WEP for very old ones, or No password for an open network.
- Type the password, and tick This network is hidden if the router does not broadcast its name.
- Download the code and print it, then scan it with a phone that is not yet on the network to check that it joins.
Example
A guest network and the text stored in the code. Each part of the result matches one field of the form.
Wi-Fi network
29 × 29 squaresWhat is typed in
- Network name (SSID)
- Cafe Guest
- Security
- WPA, WPA2 or WPA3 (most networks)
- Password
- welcome-2026
What the code stores
WIFI:T:WPA;S:Cafe Guest;P:welcome-2026;;
Good to know
- Anyone who can see the code can read the password from it. Use a guest network for printed codes in public places, and keep your main network's code private.
- If you change the password or the name, the old code stops working and you need a new one.
- Business networks that sign in with a username (WPA2-Enterprise) are not covered. The code carries one shared password, not an account.
Questions people ask
Is my Wi-Fi password sent anywhere?
No. The password is used by the page in your browser to draw the code and nothing else. It is not uploaded, stored or logged, and the download file is named qr-code-wifi, never after your network.
Which security type should I choose?
Choose WPA, WPA2 or WPA3 for any modern router. Pick WEP only for an old network that really uses it, and No password for an open network. If you are not sure, look at the Wi-Fi settings on a connected device: it shows the security type.
The phone says it cannot join. What is wrong?
Check the network name and the password against the router, because a wrong capital letter fails silently. Make sure the security type matches, and tick the hidden box only if the network really hides its name. Also check that the phone is in range of that router.
Can I make the code for a hidden network?
Yes. Tick This network is hidden. The code then tells the phone to look for the network by name even though it is not broadcast, which is how a hidden network has to be joined.
Where should I put the printed code?
Somewhere guests can scan it at arm's length, such as a frame on the counter or a card in a guest room. Print it at least 3 cm wide, keep it flat and matt, and add the network name beside it in plain text for people who cannot scan.
