Wi-Fi QR Code Generator

A Wi-Fi QR code holds your network name, password and security type in a short piece of text that phones recognise, such as WIFI:T:WPA;S:Cafe Guest;P:coffee-2026;;. When a phone scans it, it offers to join the network, and the guest never has to type the password.

• iPhone and iPad: open the Camera app and point it at the code (iOS 11 and later). Tap the banner that appears, then Join.
• Android: point the camera at the code on Android 10 and later, or use Google Lens. Most phones also have a scan icon on the Wi-Fi settings screen.

Scanning doesn’t need an internet connection or an app, and the code doesn’t point to a website: the details are in the pattern itself, so the code works for as long as the network name and password stay the same.

The name and password have to match exactly, including capitals and spaces. If you don’t know them:

• The router’s sticker usually shows both, labelled something like SSID or Network name, and Password, Wireless key or WPA key. This only applies if nobody has changed them since the router was set up.
• An iPhone that’s already connected (iOS 16 or later): go to Settings, then Wi-Fi, tap the ⓘ next to the network, then tap Password.
• An Android phone that’s already connected: open the network in Wi-Fi settings and tap Share. It shows a QR code, and on many phones the password too.

Routers often broadcast separate names for their 2.4 GHz and 5 GHz bands, such as Home and Home-5G. Make the code for the one you want guests on.

Tick Hidden network if the network doesn’t appear in phones’ lists of nearby networks. The code then tells the phone to look for it by name.

The form checks for details that can’t work, such as a WPA password shorter than 8 characters, and handles the backslashes that semicolons, commas, colons and quotes in a name or password need.

Download card makes a portrait PNG: “Scan to join the Wi-Fi”, the code, then the network name and password in large type, for anyone whose phone can’t scan. It uses your chosen colours, so keep them dark on light.

• Print the code at least 3 cm (1¼ inches) across. The card is 1,000 pixels wide, which prints sharply at A6 or postcard size.
• Put it where guests will see it: by the door, in a holiday let’s welcome folder, on café tables or a meeting room wall. A laminated card or a small frame lasts longer.
• Scan the printed card with an iPhone and an Android phone before putting it out.
• Several cards on one page? Turn them into a PDF and print them together.

Anyone who scans the code, or photographs it, can read the password: phones will display it. So, for codes on public display:

• Use a guest network. Most routers can run one, keeping visitors away from your own computers, printers and smart devices.
• Change the password now and then, and print a new card. The old code stops working straight away.
• Never use the password for anything else, such as the router’s admin login.

The code is made in your browser on your own device. Your network name and password aren’t sent anywhere, and they aren’t saved on the device either: close the page and they’re gone. See our privacy policy.
