About WiFi QR Code Generator -- Share Your WiFi Instantly
Create a QR code for your WiFi network so guests can connect by scanning with their phone. No password typing needed -- works with WPA, WPA2, and WPA3.
How to use
- Enter your WiFi network name (SSID) exactly as it appears in your router settings or in your device's WiFi list. The SSID is case-sensitive --
MyNetwork and mynetwork are treated as different networks. If your network name contains special characters like quotes or semicolons, enter them exactly as they appear and the tool will handle the encoding automatically in the QR code data string.
- Select your security type from the dropdown. Most modern home networks use WPA2 or WPA3 -- check your router's admin page if you are not sure. WPA/WPA2 is the most common and works with virtually all devices. WPA3 is the newest standard offering stronger encryption, but older devices may not support it. WEP is a legacy protocol that is no longer considered secure and should be avoided. If your network has no password (like a guest network with a captive portal), select None.
- The QR code generates automatically as you type, updating in real time. Once it looks correct, you can download it as a PNG image to save on your phone, email to guests, or print it. For physical display, print the QR code and place it near your router, on a fridge magnet, in a guest room, or at a reception desk. The image is high-resolution enough for printing at any size from a small sticker to a letter-sized sheet.
- Guests connect by opening their smartphone camera app and pointing it at the QR code. On iPhone (iOS 11 and later), a notification banner appears at the top of the screen -- tap it to join the network automatically. On Android (version 9 and later), a popup appears with the option to connect. The entire process takes about 3 seconds and eliminates the need to spell out long passwords, deal with uppercase/lowercase confusion, or manually type complex passphrases.
Frequently asked questions
How do guests use the QR code to connect?
Guests simply open the default camera app on their smartphone and point it at the QR code. On iPhone running iOS 11 or later, a notification banner appears at the top of the screen saying "Join [network name]" -- they tap it and the phone connects automatically. On Android 9 and later, a similar popup appears with the network details and a connect button. No third-party QR scanner app is needed -- the built-in camera handles WiFi QR codes natively. The phone reads the encoded network name, password, and security type from the QR code and connects in about 3 seconds, completely bypassing the manual WiFi settings screen.
Is my WiFi password stored or sent anywhere?
No -- your WiFi credentials are completely safe. The QR code is generated entirely within your browser using JavaScript. Your network name and password are encoded into the QR image locally on your device and are never transmitted to any server, API, or third-party service. You can verify this by disconnecting from the internet and using the tool offline -- it works exactly the same way. The generated QR code contains a standard WiFi configuration string (in the format WIFI:T:WPA;S:NetworkName;P:Password;;) that is recognized by all modern smartphones. Your credentials exist only in the QR image itself.
What security types are supported?
The generator supports all standard WiFi security protocols. WPA/WPA2 is the most widely used -- select this if your router is set to WPA2-Personal or WPA-PSK, which covers the vast majority of home and small business networks. WPA3 is the latest security standard with stronger encryption (SAE handshake instead of PSK), but requires that both your router and the connecting device support WPA3. WEP is included for legacy compatibility but is cryptographically broken and should not be used for any network that handles sensitive data. None creates a QR code for open networks with no password, useful for guest networks that use a captive portal for authentication.
Can I print the QR code for display?
Yes -- the download button saves the QR code as a high-resolution PNG image that prints cleanly at any size. For a guest room or reception area, print it on a standard sheet of paper and frame it or tape it to the wall. For a more permanent display, print it as a sticker or laminated card. The minimum recommended print size is about 2x2 centimeters (roughly 1 inch square) for reliable scanning. Larger sizes scan faster and work from greater distances. You can also add the PNG to a Word document, presentation slide, or email signature if you want to share digitally.
Does the QR code expire?
The QR code itself never expires -- it is a static image encoding your network credentials. However, if you change your WiFi password or network name on your router, the old QR code will no longer work because it contains the outdated credentials. In that case, simply generate a new QR code with the updated information and replace the old printout. This also means you should update your displayed QR codes whenever you rotate your WiFi password for security. Some security experts recommend changing your WiFi password every 6-12 months, especially if you have shared it with many guests over time.
What if the QR code does not work on someone's phone?
If a guest's phone does not recognize the QR code when scanned with the camera app, there are a few common causes. First, ensure the phone's OS supports WiFi QR codes natively -- iPhones need iOS 11+ and Android devices need version 9+. Older phones may need a dedicated QR scanner app like Google Lens. Second, check that the QR code is printed or displayed clearly without glare, shadows, or distortion. Third, verify that the security type in the QR code matches your router's actual setting -- for example, if your router uses WPA3 but the QR code was generated with WPA2 selected, some devices may fail to connect. If the guest is using a very old device, they may need to connect manually using the password.
Is this useful for businesses and Airbnbs?
Absolutely -- WiFi QR codes are one of the simplest hospitality upgrades for any business, rental property, or shared space. Airbnb and vacation rental hosts can print the QR code and place it in a welcome guide or frame it on the wall, eliminating the most common guest question. Restaurants and cafes can display it on table tents or near the counter so customers connect without asking staff. Offices can post it in meeting rooms for visitors. The QR code also avoids the security risk of writing your password on a whiteboard where anyone can photograph it -- guests get the credentials directly into their device's WiFi settings without ever seeing the actual password text.
