How to Make a QR Code for Your Wi-Fi
Typing a long Wi-Fi password on a phone keyboard is slow and error-prone, especially for guests. A QR code carries the network name, password and security type in one scan, so a visitor joins in seconds.
What the code needs
- The exact network name (SSID), including capital letters and spaces.
- The password, exactly as set on the router.
- The security type — usually WPA or WPA2 on a modern router. Check the router settings if you are unsure; guessing wrong is the commonest reason a code fails.
Make it and test it yourself
Generate the code, then scan it with your own phone before you print or share it. If your phone joins the network, the code is right. If it does not, re-check the name and password character by character — one wrong letter is enough.
Share it sensibly
Anyone who can scan the code can join your network, so treat a printed code like a spare key. Keep it inside your home, and if you change the Wi-Fi password, make a new code and throw the old one away. For a guest network, use the guest password rather than your main one, and the risk stays small even if the code travels.
The Wi-Fi QR tool is a guide only — it does not generate the code itself yet. The steps above are the same ones it will follow.
