Как создать QR-код для Wi-Fi

To make a Wi-Fi QR code, type one line in this format into the free QR code generator: WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;. Replace the network name and password with your own, download the PNG and print it. Guests point their phone camera at it and tap to join, with no password to read out or mistype. The code is made on your device, so your Wi-Fi password is never uploaded.

Wi-Fi QR codes are perfect for homes with lots of visitors, guest rooms, cafes, offices, clinics, homestays and classrooms. The only trick is getting that one line exactly right.

The Wi-Fi QR format

Phones recognise a QR code as a Wi-Fi network when its text follows this pattern:

WIFI:T:<security>;S:<network name>;P:<password>;;

Each part is a letter, a colon, the value and a semicolon, and the whole thing ends with two semicolons.

Part	What it means	What to type
T:	Security type	WPA for WPA and WPA2 networks (most home routers), WEP for very old routers, or nopass for an open network
S:	Network name (SSID)	Exactly as it appears in your phone's Wi-Fi list, including capitals and spaces
P:	Password	Exactly as set on your router. Leave it out for an open network
H:	Hidden network (optional)	H:true; if your network doesn't broadcast its name

Примеры

A typical home network called Sharma Home with the password Blue#Sky2026:

WIFI:T:WPA;S:Sharma Home;P:Blue#Sky2026;;

An open cafe network with no password:

WIFI:T:nopass;S:Cafe Guest;;

A hidden network:

WIFI:T:WPA;S:Studio5G;P:my-long-password;H:true;;

Special characters

Five characters have a special meaning in this format: the backslash \, semicolon ;, comma ,, colon : and double quote ". If your network name or password contains any of them, put a backslash in front of each one. A password of tea;time is written P:tea\;time;. Other symbols, such as #, @, ! and spaces, need no change.

Step by step

1. Find your exact network name and password. They're often on a sticker on the router, or in the router's settings page.
2. Write the line in the format above. Check capital letters: network names and passwords are case-sensitive.
3. Open the free QR code generator and paste the line into Link or text, replacing the sample link.
4. Watch the preview update, then click Download PNG.
5. Test it: open your phone's camera, point it at the code on screen, and tap the notification to join. Test with both an iPhone and an Android phone if you can.
6. Print it and put it where guests will see it.

The generator doesn't have a separate Wi-Fi form, which is why you type the line yourself. The upside is that you can see exactly what's in the code, and nothing about your network leaves your device.

Which phones can scan it?

Recent iPhones and most Android phones can read Wi-Fi QR codes straight from the built-in camera app. On some Android phones the option is in the camera's lens or scanner mode, or in Google Lens. When the phone recognises the code, it shows the network name and a button to join.

Many Android phones can also show a QR code for the network they're already connected to: look for a Share option in the Wi-Fi settings. That's a quick way to pass the network on from a phone, while a printed code from EveryApp works for everyone without anyone needing to unlock a phone.

Troubleshooting

The phone sees the code but won't connect. Check the password and network name letter by letter, including capitals and spaces. Then check that T: matches your router's security. If your router is set to WPA3 only and the code doesn't connect, try switching the router to WPA2/WPA3 mixed mode.

The phone shows the text instead of a join button. The line probably doesn't start with WIFI: in capitals, or a semicolon is missing. Make sure it ends with ;;.

It worked, then stopped. If you change your Wi-Fi password, the code still has the old one. Make a new code each time the password changes.

Keep your network safe

Anyone who scans the code can read the password inside it, and so can anyone who photographs the printed sheet. A few habits help:

• Use a guest network for visitors if your router supports one. It keeps guests away from your computers, printers and smart devices.
• Use a strong password. A Wi-Fi QR code means nobody has to type it, so it can be long and random. The free password generator makes one in a click, and the guide on creating a strong password explains what makes one strong.
• Don't display it in public view if the network is private. Inside a guest room or on the fridge is fine; facing a shop window isn't.

Print and display ideas

• A framed card in the living room or guest room.
• A table tent in a cafe or restaurant, with the network name printed under the code.
• A laminated sheet at a clinic or office reception.
• Inside a homestay welcome folder.
