計算例
Guest network for a holiday let
Network name Cottage Guest, password Harbour-Walk-27, WPA security
A QR code that encodes WIFI:T:WPA;S:Cottage Guest;P:Harbour-Walk-27;;
Scanning the code offers to join the network, so guests never need to type the password.
Open network with no password
Network name Cafe Guest, no password, and open security selected
A QR code that encodes WIFI:T:nopass;S:Cafe Guest;;
An open network needs no password, so the code carries only the name.
Wi-Fi QR Code Generator について
A Wi-Fi QR code lets guests join your network by pointing a phone camera at a square code, instead of typing a long password. Enter the network name and password, choose the type of encryption, and the code appears straight away. Most modern home and office routers use WPA2 or WPA3, which the WPA option covers. A printed code by the router or on a welcome card saves time and avoids spelling mistakes, especially with long passwords that mix capitals, numbers and symbols.
The network name is the one that appears in the list of available networks, and capital letters and spaces count. Type it exactly as it appears on your own devices. Tick hidden network only if your router does not broadcast its name. Choose No password for an open network, such as a guest network that needs no password at all. Keep the printed code somewhere that only people you trust can see, and make a new code with a new password if the old one is shared more widely than you intended.

よくあるご質問
Which encryption should I choose?
Choose WPA for most networks, because the code format covers WPA, WPA2 and WPA3. WEP is an older type used by very old routers, so if your router supports a newer type, choose that instead. No password is only for open networks that anyone may join, which may suit a casual guest network but is rarely the right choice for a home network.
Will the code work on iPhone and Android?
Yes. Modern phone cameras read Wi-Fi QR codes and offer to join the network with a single tap. Older phones may need a scanning app. If a camera does not offer to join, check that the password is typed correctly and that the encryption type matches your router, then try again with the code printed a little larger.
Why does the code include my password?
A Wi-Fi code has to include the password so that a phone can join the network. Anyone who scans the code can join, so display it only where people you trust can see it, and change the password if the code is shared more widely than you intended. The code keeps the details in the standard Wi-Fi format that phones understand.
Why will a phone not recognise my code?
Check the network name and password for typos, especially spaces and capital letters. Characters such as semicolons, commas, colons and backslashes are handled automatically, but a mistype is easy to miss. Make sure the encryption type matches your router, and try a larger print with strong contrast if the camera struggles to read the code.
Can I use this for a hidden network?
Yes. Tick the hidden network option and the code tells the phone to join a network whose name does not show in its list. The network still needs the correct password and encryption type to connect, so check those carefully before printing the code for guests to use.
