WiFi QR Code: Let Guests Join Your Network Without Typing a Password
A WiFi QR code can save guests from typing a password, but it also puts network credentials into a scannable image. Here is how to make one, test it, and decide where it is safe to display.
Before making a code, decide which network visitors should use. For a business or rental, a separate guest network is usually a better choice than sharing the same network used by work computers, cameras, or other private devices. A QR code makes access convenient; it does not limit who can copy or forward the credentials.
What the code contains
A WiFi QR code encodes connection details such as the network name (SSID), security mode, and—when the network is password-protected—the password. A compatible phone may offer to join after scanning, but the exact prompt and supported security modes vary by device and software version.
This generator builds the code in your browser. The QR content is not submitted to our website by the generator. Once downloaded or printed, however, the code itself contains the details needed to attempt a connection. Treat the image like a password card.
What you need
- Network name (SSID). Copy the exact name shown in the device's WiFi settings. Capitalization and punctuation matter.
- Password. Use the current password for the network you intend guests to join. Do not use the router's administrator password.
- Security mode. Select the mode that matches the router. If you are unsure, check the router settings or ask the network administrator instead of guessing.
Create and verify the code
- Open the QR code generator and choose WiFi.
- Enter the guest network's SSID, matching the spelling and capitalization exactly.
- Select the network's actual security mode and enter its WiFi password. The password is not the router admin login.
- Enable Hidden network only when the SSID is intentionally hidden in the router settings.
- Download the code and scan it with a device that is not already connected to that network. Confirm the device joins the intended guest network.
Device compatibility
Many recent phones can recognize WiFi QR codes with their camera or a built-in QR scanner, but support differs across models, operating-system versions, and camera apps. Test with the kinds of phones your guests are likely to use. If a camera only displays text or does not offer a join prompt, provide a way to connect manually.
Where to display it
| Place | Idea |
|---|---|
| Home | Share only with the people you want on that network; consider a guest network for visitors. |
| Rental property | Place instructions inside the property and rotate guest access between stays if your router supports it. |
| Café or waiting room | Use an isolated guest network and display the code where customers can scan it without taking the card. |
| Office | Use a visitor network approved by the network administrator, not an internal staff network. |
Security tips
Anyone who can scan or photograph a visible code can read its embedded credentials. Reduce the impact of sharing it:
- Use an isolated guest network. Enable the router's guest isolation or equivalent setting where available, and ask an administrator to configure it for an office network.
- Limit who can photograph or access the code. Avoid publishing a password-bearing code on a public website or social profile.
- Rotate credentials when access should end. If you change the SSID or password, generate and display an updated QR code; the old printed code still contains the old details.
- Choose a secure router configuration. Use the strongest security mode supported by your devices and router; avoid legacy modes unless required for compatibility.
Troubleshooting
The scan is recognized but joining fails. Recheck the SSID, password, and security mode against the router settings. Confirm the network is in range and accepting new connections.
The camera does not offer to join. Try the phone's built-in QR scanner or WiFi settings, and check whether that model supports WiFi QR import. Keep manual connection instructions available.
The code used to work. The network name, password, or security mode may have changed. Create a replacement code and remove old copies that could confuse guests.
