Create a Wi-Fi QR code for guests

Open Wi-Fi QR code

A Wi-Fi QR lets a compatible phone read the network details without someone typing a long password. It is useful at a reception desk, in a meeting room or at home. Use a guest network when your router offers one, and share the code with the people who should have access.

Check the network details

You need the exact network name, its security type and its password. Copy the name as it appears in the Wi-Fi settings, including capitals and spaces. A QR cannot fix an incorrect password or make an out-of-range network available.

Minutil provides WPA / WPA2 Personal, WEP and Open network options. Choose the setting that matches the network you already have. WEP is a legacy compatibility option, not a recommendation to weaken your router's security. Enterprise networks with individual logins or certificates need a different setup.

Make and download the QR

  1. Open Wi-Fi QR code

    Enter the Network name (SSID), select Security and enter the Wi-Fi password if the network requires one.

  2. Match the hidden-network setting

    Select Hidden network only if that is how the router is configured. A hidden network can behave differently across scanning apps and devices.

  3. Check the generated preview

    The preview updates from the details you enter. Keep a dark code on a light background and preserve the clear margin around it.

  4. Download PNG or SVG

    PNG is useful for inserting into a document. SVG can scale for print without pixelating; make sure your design or printing software supports it.

Test it before making a stack of signs

Scan the code with another phone. If that phone already knows the network, it may connect without testing the encoded password, so use a device without saved credentials or forget the network first when appropriate.

Then print one copy at the intended size. Scan it from the distance and lighting where guests will use it. Avoid folds, reflections and anything covering the code. If a scan reads the details but the phone does not connect, check the router settings and network availability as well as the QR.

Treat the QR like the password

A Wi-Fi QR contains the credentials; it does not encrypt them or hide them from someone who can scan it. Minutil generates the code on your device, but the downloaded image can still reveal the network details to anyone who receives it.

Changing the router's password does not update a printed QR. Generate and distribute a new code when the name, password or security type changes, and remove outdated copies.
