Create a Guest Wi-Fi QR Code and Print a Sharing Card

Make a QR code for guest Wi-Fi access, test it with another phone and understand the password-sharing risks.

Understand the problem

A Wi-Fi QR card saves guests from typing a password. It does not protect the credentials: anyone who decodes the QR can read the stored network information.

How to solve it

  1. Choose a network that is safe to share

    If you have a separate guest network, use that instead of private office credentials. Check the exact network name and security type on your device.

  2. Enter the network name and credentials carefully

    SSID capitalization, special characters and passwords must match the network settings. Select the correct security type or the no-password option.

  3. Test with a second phone before publishing

    Scan the generated code on another device to confirm the correct network is offered. Only display the card where visitors should receive access.

Another way to do this

Many devices offer their own Wi-Fi sharing features. You can use those for one-off visitors when printing a public QR card is unnecessary.

When the method may not work

A QR code does not encrypt or hide the credentials it carries. Do not publicly post credentials intended for a restricted network.

Frequently asked questions

Can someone retrieve the password from a Wi-Fi QR image?

Yes. A QR decoder can read the included connection details, so treat public posting as sharing those credentials with viewers.
