WiFi QR Codes: Share a Guest Network More Safely
How WiFi QR payloads work, which characters need escaping, and what to test before displaying one.
A WiFi QR code can carry a network name, password, and security mode. Compatible scanners can use that payload to offer a join-network action.
Use a guest network
A WiFi QR code contains the credentials needed to join the network. Anyone who can scan or photograph the code may be able to recover those credentials. Use an isolated guest network rather than exposing the password for internal devices.
Payload structure
A common payload shape is:
WIFI:T:WPA;S:Guest Network;P:example-password;;
Backslashes, semicolons, commas, colons, and quotation marks inside the network name or password must be escaped so they are not mistaken for field separators.
Before displaying the code
- Verify the network name and security mode.
- Scan the exported image with the devices your visitors are likely to use.
- Test in the final print size and lighting.
- Replace the displayed code when the guest password changes.
- Keep a written connection option for people who cannot scan the code.
GetQrivo release scope
The current GetQrivo web utility creates the WiFi payload locally and exports it as PNG, SVG, or PDF. It does not store the network credentials or provide a hosted destination that can be edited later.
Use the local QR generator
Create URL, text, WiFi, email, phone, SMS, contact, and calendar-event QR codes, then export PNG, SVG, or PDF without an account.
