Make QR practical guide
How to Create, Share and Scan a Wi-Fi QR Code
A Wi-Fi QR code carries your network name, security setting and password. It can make joining a guest network easier, but it does not create internet access or discover a password you do not know. Start with credentials for a network you own or have permission to share.
Create a Wi-Fi password QR code
Open the Wi-Fi generator and enter the network name (SSID) exactly, including capitalization and spaces. Choose the security setting that matches your router and enter the password. Select Open network only when the network really has no password. A password-free QR for a protected network will not bypass its security.
The QR uses the common WIFI text format with fields for security, network name and password. Make QR escapes special characters in the fields for you, so enter the real credentials rather than a hand-written WIFI payload. Compatibility depends on the scanner, device and router; a security label in the editor is not a guarantee that every phone can join.
Print a Wi-Fi QR sign for guests
Use a dedicated guest network where your router provides one. The Wi-Fi card template can place a readable network label and scanning instruction beside the QR. Visible words and the encoded credentials are edited separately: check both before printing. PNG is useful for an image, SVG for scalable artwork and PDF for the template's print size.
Preserve the white border, use a dark QR color and test the sign at its intended size. Put the sign where guests can reach it with a camera. A browser draft makes a future replacement easier, but when the password changes you must export and replace the printed code. The downloaded QR has no built-in expiry; obsolete credentials still stop it working.
Scan the code and join the network
Try the receiving phone's camera or built-in QR reader. If it recognizes the Wi-Fi data, it may offer a join-network action for the user to confirm. Names and locations of device controls vary. If the camera displays raw text or no join option, use that device's Wi-Fi settings and enter the credentials manually. A laptop browser scanner can read the data without being able to join the network itself.
Test with a phone that is not already connected. Check that the network is in range, Wi-Fi is enabled and the router accepts the credentials. A guest portal, enterprise login or device-specific setup may require more than a conventional password QR. This guide does not provide model-specific instructions for individual routers, cameras or phones.
A Wi-Fi QR scanner can reveal the password
Use Make QR's image-upload scanner to check your own exported code. It decodes the content locally in your browser and can display the embedded network details, including the password. Reading an existing QR is different from retrieving an unknown router password. Only inspect codes you are authorized to use, and avoid uploading a credential-bearing image to a public sharing page.
Anyone who can scan a Wi-Fi sign can potentially read its credentials. Hiding the printed password or covering the text does not encrypt the QR. Keep a private network's code private; share a guest network deliberately and replace the sign when access should change. A QR code cannot give free internet, bypass a password or hack a router.
