Do Wi-Fi QR codes work on iPhone and Android?

Yes. The iPhone Camera app recognises Wi-Fi QR codes and offers to join, and most Android phones do the same with the camera app, Google Lens or the scan option in Wi-Fi settings.

Is it safe to put my Wi-Fi password in a QR code?

The code is made in your browser and not sent anywhere. But anyone who can scan it can join, and anyone with a QR reader can see the password — so only display it where you'd happily share the password itself.

Does a Wi-Fi QR code expire?

No. It's a static code with the network details inside the image. It works until you change the network name or password.

Which security type should I choose?

WPA/WPA2/WPA3 for almost every home and office router. Choose WEP only for very old equipment, and None only if your network has no password.

How to Create a Wi-Fi QR Code (Share Your Password)

3 min readUpdated 5 October 2026

To create a Wi-Fi QR code, open QR Generator, choose Wi-Fi, type your network name and password, pick the security type and press Download PNG. Guests point their phone camera at the code and join without typing anything.

It's free, needs no account and works on any device with a browser. The code is generated on your own device, so your Wi-Fi password is never sent to a server — and because the details live inside the image itself, the code never expires.

Step by step

1Choose Wi-FiOpen the QR Generator and pick Wi-Fi from the list of code types at the top.
2Enter the network nameType your Network name (SSID) exactly as it appears in your phone's Wi-Fi list, including capitals and spaces.
3Pick the security typeUnder Security, choose WPA/WPA2/WPA3 for almost any modern router, WEP only for very old equipment, or None (open) for a network without a password.
4Add the passwordType the Password — use the eye icon to check it for typos. If your network doesn't broadcast its name, switch on Hidden network.
5Test, then saveScan the preview with your own phone to make sure it joins. Then press Download PNG, download an SVG for print, or Copy the image to paste into a document.

How guests join by scanning

On iPhone, open the Camera app and point it at the code; a notification appears offering to join the network — tap it. Most Android phones do the same through the camera app or Google Lens, and many also have a QR scan option in Wi-Fi settings next to Add network.

Laptops generally can't join from a QR code. Scan it with QR Scanner on a phone or from a screenshot to see and copy the password, then type it in.

Printing it for a home, café or office

A Wi-Fi code on a table card or the fridge saves a lot of spelling out passwords. For a code that scans first time:

Keep it dark on light — light codes on a dark background don't scan in some apps, and the tool warns you about this and about low contrast.
Leave the white border around the code (the Quiet zone under More options); scanners need it.
Print it at least a few centimetres wide, and use SVG or a large PNG size so it stays sharp at any size.
Add a line of text underneath with the network name, for anyone whose phone can't scan.

Tip: For a shop or office, consider putting the QR code on a separate guest network, so visitors never get access to your main network.

If the code doesn't connect

If the phone reads the code but fails to join, the details don't match the router. Check the network name and password letter by letter — both are case-sensitive — and make sure the security type is right. Special characters such as ; , : and quotes are handled for you.

Changed your Wi-Fi password? A QR code can't update itself, so make a new one and replace the printed copy.

More QR codes you can make

The same tool makes codes for links, text, email, phone numbers, SMS and contact cards. For payments in Thailand, use PromptPay QR. Need a stronger Wi-Fi password first? Password Generator creates one in a click.
