Sobre esta ferramenta
A Wi-Fi QR code encodes your network name, security type and password in a standard format that iOS and Android both recognise natively. Point a camera at it and the phone offers to join - no dictating a 20-character password across a room, no guests typing it wrong three times. The format itself is simple and worth understanding, because it explains the one thing people get wrong: the password is stored as plain text inside the code. It is not encrypted or hidden, merely encoded, so anyone who scans the code can read the credentials. That is fine for a café or a home guest network, where you would tell people the password anyway. It is not fine for a code left on public display leading to a network with your file shares on it. The right approach for anywhere semi-public is a separate guest network, which most routers support. Codes are generated in your browser and nothing is transmitted.
Como usar esta ferramenta
- Enter your network nameThe SSID exactly as it appears, including capitals - it is case-sensitive and a mismatch simply fails to connect.
- Choose the security typeWPA/WPA2 covers virtually every modern network. Pick "none" only for a genuinely open network.
- Enter the passwordType it carefully. The QR code cannot be corrected after printing, and a wrong character means it never works.
- Test before displaying itScan with both an iPhone and an Android device, then print or display it.
Por que usar
- Guests join by pointing a camera - no dictating or mistyping a long password.
- Works natively in the iOS and Android camera apps with no app to install.
- Long, genuinely strong passwords become practical, because nobody has to type them.
- Generated in your browser, so your network credentials are never transmitted.
- Printable at any size for a wall, table card or window.
Usos comuns
- A café, restaurant or salon offering guest Wi-Fi on a table card.
- An office reception or meeting room for visitors.
- A holiday let or guest room, printed and framed on the wall.
- An event or conference venue.
- Home use, so visitors stop asking for the password.
Dicas para melhores resultados
- Use your guest network, not your main one. Most routers provide one, and it keeps visitors off the network your devices and files are on.
- Because nobody has to type it, make the guest password long and random - a QR code removes the usual reason people choose weak passwords.
- Check the SSID capitalisation carefully. It is case-sensitive and the most common reason a generated code fails.
- Test on both iPhone and Android before printing. They handle the format slightly differently.
- If you change the Wi-Fi password, the printed code stops working - reprint it, since the code cannot be updated.
Erros a evitar
- Displaying a code for your main network in a public space, which hands out access to everything on it.
- Assuming the password is hidden because it looks like a pattern. Anyone who scans the code can read it in plain text.
- Getting the SSID case wrong, so the code looks fine and never connects.
- Printing the code too small for the distance people scan from.
- Forgetting the code is fixed - change the password and every printed copy becomes useless.
Perguntas frequentes
Enter your network name, security type and password above, then download the code. Scanning it with any modern phone camera prompts to join the network.
Yes. No account, no expiry and no watermark - and your credentials never leave your browser.
No. It is encoded, not encrypted, so anyone who scans the code can read the password in plain text. Treat the code exactly as you would treat writing the password on the wall.
Only for a guest network. Anyone who can see the code can join, so use the separate guest network most routers provide rather than the one your computers and file shares are on.
WPA and WPA2, which covers virtually all modern networks, plus open networks with no password. WPA3 devices generally connect using the WPA2 setting.
Current iPhones and Android phones recognise Wi-Fi QR codes directly in the camera app. Very old devices may need a dedicated scanning app, which is why testing on a couple of phones is worth the minute it takes.
Almost always the SSID capitalisation - network names are case-sensitive. After that, check the security type matches and that the password has no typo or trailing space.
No. The data is fixed in the pattern, so a password change means generating and reprinting a new code.
