Quick answer: Enter your network name, password, and security type above, then download the code. Guests scan it with their phone camera and tap the join prompt. The details are encoded in your browser and never uploaded.
How to create a Wi-Fi QR code
- Enter the exact network name (SSID). SSIDs are case-sensitive. Copy the name from your router settings if you are not sure.
- Add the password and choose the security type. WPA / WPA2 is the right choice for most networks. Use “No password” only for an open guest network.
- Download and test before printing. Scan the code with an iPhone and an Android phone, join the network, and load a page. Then print it at a size that is easy to scan.
What is a Wi-Fi QR code?
A Wi-Fi QR code stores the network name, password, and security type in a standard text format. When a phone scans it, the camera or scanner app can offer to join the network automatically. The guest does not have to find the Wi-Fi settings screen, select the network, and type the password.
This is a static QR code. The network details are encoded in the pattern itself, not stored on a server. That makes it private and fast, but it also means the code cannot be changed after it is printed. If the password changes, you need a new code.
Where a Wi-Fi QR code helps
- Cafés and restaurants: put the code on tables or near the counter so customers can join a guest network without asking staff.
- Guest rooms and rentals: add the code to a welcome card or fridge note so guests do not have to search for the router label.
- Offices and studios: let visitors, freelancers, and clients connect to a dedicated guest network.
- Events and pop-ups: share a temporary network with attendees without reading the password to every person.
- Home: make it easier for family and friends to join without digging through a drawer for the router manual.
Tips for a code that actually connects
Use the exact SSID
A single wrong character or a capitalization difference will stop the phone from finding the network. If your router hides the SSID, turn on the hidden network option in the generator.
Choose the right security type
WPA / WPA2 is the safest default for modern networks. WEP is only for old hardware and is not secure. Open networks do not need a password, but they also do not protect your guests' traffic. For a business, a separate guest network with its own password is usually the better setup.
Test on both iPhone and Android
Camera apps and scanner apps do not all behave the same way. Test the code on at least one iPhone and one Android phone before you print a hundred copies. Some third-party scanner apps do not support Wi-Fi joining at all.
Print it large enough
A Wi-Fi QR code carries more data than a short URL, so it needs a little more space. Aim for at least 3 × 3 cm (1.2 × 1.2 in) for a table card, and larger for a poster or a code that people scan from a distance. Keep the white quiet zone around the code.
Treat the password as public
Anyone who can scan the code can read the password. Use a guest network for customers, avoid putting the code where it can be photographed from outside, and change the password if the code spreads further than you intended.
Static means fixed
If you change the Wi-Fi password, the old code keeps advertising the old one. Print a new code or use a stable guest-network password that you do not change often.
Wi-Fi QR code vs. a password card
A password card is easier to read for someone who is already inside, but it still requires typing. A QR code is faster and less error-prone, especially for guests who do not speak the local language or are using a phone with a cracked screen. The trade-off is that the password is visible to anyone who scans it.
