How to make a Wi-Fi QR code for guests

Use a guest network when possible

Anyone who scans a Wi-Fi QR code can read the connection details it contains. For a café, home office or shared space, create a separate guest network first if your router supports one. That keeps visitor devices separate from the network you use for personal devices or business equipment.

Only create a code for a network you own or are authorised to share. A QR code makes joining easier. It does not add security beyond the network settings already in place.

Create the Wi-Fi QR code

Open Qraffe’s Wi-Fi QR code generator and enter the network name, security setting and password exactly as they appear in your router settings. Mark the network as hidden only when it is actually hidden.

If you later change the network name, password or security setting, make a new QR code. The original static code cannot update itself.

1. Open the Wi-Fi QR code generator.
2. Enter the network name exactly.
3. Choose the matching security setting.
4. Enter the password including capital letters and special characters.
5. Generate the code and download PNG or SVG for the place you plan to use it.

Test the exact code before displaying it

Scan the downloaded or printed version with more than one phone. Confirm that the network name is correct and that the phone offers the expected connection prompt. Camera support varies, so a guest may still need to join the network manually on some devices.

Qraffe can check the QR image locally. It cannot confirm that your router accepts the password or that every phone handles the connection in the same way.

Display it where guests need it

Put the code where people ask for access: near a reception desk, in a guest room, on a table sign or beside a workspace. Add a plain label such as “Scan to join guest Wi-Fi” so people know what will happen before scanning.

Keep a clear margin around the code, use strong contrast and test it under the same lighting conditions where guests will use it.
