Create a Wi-Fi QR Code – connect guests without a password

You know how it goes. Guests arrive and the first thing they ask for is the Wi-Fi password. You tell them, they type it in, make a typo, ask again. There has been an elegant solution to this for years: a Wi-Fi QR code. One scan – and the device connects automatically.

How does a Wi-Fi QR code work?

A Wi-Fi QR code contains your network details in a standardised format – network name (SSID), password, and encryption type. When someone scans the code, their smartphone recognises the WIFI format and automatically offers to connect to the network. The user taps "Connect" – done, without typing a password.

This works on all modern iPhones and Android devices without any additional app.

Creating a Wi-Fi QR code – step by step

1. Open QRHero.de
2. Select the "Wi-Fi" or "WLAN" type
3. Enter your network details:
   • SSID (the name of your Wi-Fi network)
   • Password
   • Encryption (almost always WPA/WPA2)
4. Customise the design – colour, logo (optional)
5. Download and print

Important: test the code before printing. Scan it with a device that is not yet logged into the network.

Where to use a Wi-Fi QR code

Restaurants and cafés: The classic use case. A laminated table tent saves you and your staff time every single day.

Airbnb and holiday rentals: Stick the code in the welcome booklet or in a clearly visible spot. Guests are connected immediately without having to call you.

Offices and co-working spaces: Visitors and new employees need Wi-Fi immediately. A code in the entrance area or at reception solves this permanently.

Events and venues: Display the QR code on a screen or print it on place cards. A hundred guests connect simultaneously – no bottlenecks.

Waiting rooms and medical practices: Patients are waiting anyway. A Wi-Fi code on the wall noticeably improves the waiting experience.

Retail: Customers who browse while shopping buy more. A QR code at the entrance or checkout makes your Wi-Fi accessible.

Security considerations

No guest network? Set one up. Your main network (with computers, NAS, smart home devices) should never be accessible to guests. A separate guest network can be set up in minutes on your router.

Password in a QR code – is that safe? The password is encoded in the code but not encrypted. Someone with specialist tools could read the password from the code. However, this is not a practical security concern since guests who scan the code are supposed to have access to the network anyway.

What happens when the password changes? If you change the Wi-Fi password, you need to create a new QR code and reprint it. This is the only downside of static Wi-Fi codes – plan for it.
