How do you create and safely share a Wi-Fi QR code?
Format WPA/WPA2 network details correctly, mark hidden networks, and share Wi-Fi access safely.
A Wi-Fi QR code carries the network name, security type, and password in a string such as `WIFI:T:WPA;S:NETWORK;P:PASSWORD;;`. QR64Code creates that string in the browser; sharing the code also shares the Wi-Fi password.
What changed in this update?
The Wi-Fi template, hidden-network option, and sharing warnings were reviewed together.
What fields are inside a Wi-Fi QR code?
Wi-Fi QR content contains the security type, SSID, and password in plain text. WPA/WPA2 networks use `T:WPA`; open networks use `T:nopass`. Semicolons, commas, colons, and backslashes in names or passwords must be escaped.
How do you make a Wi-Fi QR code step by step?
Choose the Wi-Fi template in the QR Code Generator, enter the network name and password, confirm the security type, and generate the code. Test with at least one iOS and one Android device. Do not crop the clear margin around a printed QR code.
Is sharing a Wi-Fi QR code safe?
A Wi-Fi QR code does not encrypt the password; a scanner can display it. Use a separate guest network, do not place the code in a public area, and change the guest password when access should end.
Frequently asked questions
Can hidden networks use a QR code?
Many devices recognize `H:true`, but support varies, so also provide manual connection instructions.
Does the QR code hide the password?
No. The password is present in the QR content and can be read by a compatible scanner.
