Quick answer
A Wi-Fi QR code stores the network name, security type, password, and optional hidden-network flag in a standard text payload. Compatible phones can scan it and offer to join without typing. The finished QR code contains the password in readable form, so use a guest network and control where the code is displayed.
How to do it
- Enter the SSID exactly, including capitalization and spaces.
- Choose the router's real security mode and add the password.
- Generate, scan with iPhone and Android, then print only after the test succeeds.
Select the correct settings
Most current personal networks use WPA2 or WPA3 and work with the WPA option. Choose no security only for an intentionally open network. Enable Hidden only when the router does not broadcast the SSID; marking a normal network as hidden can prevent a successful join.
Protect the shared password
Local generation means the password is not uploaded, but anyone who can scan or photograph the finished symbol may recover it. Put visitors on an isolated guest network, remove old printed codes after a password change, and do not display the code in a public-facing window.
Common mistakes to avoid
- Misspelling the SSID or changing its capitalization.
- Selecting WEP or open security for a WPA network.
- Treating the printed QR code as secret.
