How do I create a Wi-Fi QR code?

Step by step

1. 1 Open the Wi-Fi QR generator.
2. 2 Enter the network name (SSID) exactly as it appears, including capitals.
3. 3 Enter the password and choose the security type (WPA/WPA2, WEP or none).
4. 4 Tick "Hidden network" if your network does not broadcast its name.
5. 5 Download and print the code; test it with a phone first.

Which phones can scan Wi-Fi QR codes?

Most iPhones (iOS 11 and later) and Android phones (Android 10 and later, or using Google Lens) recognise Wi-Fi QR codes from the camera and offer to join the network.

Keep your network safe

Anyone who scans the code can join and can see the password on most phones. Put guest Wi-Fi on a separate guest network, and print a new code if you change the password.

What is inside a Wi-Fi QR code?

A Wi-Fi QR code stores your network details in a standard text format that phone cameras understand, for example: WIFI:T:WPA;S:CafeGuest;P:your-password;;. T is the security type (WPA, WEP or none), S is the network name and P is the password. Phones read it and offer to join the network.

Because the details are inside the code, anyone who scans or photographs it can see the password. Use a separate guest network for codes that are on public display.

Where to put a Wi-Fi QR code

• Café and restaurant tables, next to the menu code.
• Hotel rooms, guest houses and holiday rentals.
• Office reception and meeting rooms for visitors.
• Clinics, salons and waiting areas.
• At home, on the fridge or near the router for guests.

Troubleshooting

• Phone does not offer to join: make sure the network name and password are exactly right, including capital letters and spaces.
• Joins but no internet: the problem is the router or connection, not the QR code.
• Hidden network: tick the hidden-network option when you create the code.
• Changed the password: create and print a new code — the old one still contains the old password.
