Share your WiFi with a QR code

What is a WiFi QR code?

It is a normal QR image that encodes your network name (SSID), security type (WPA, WEP, or open), and password in a standard format phones understand. When someone scans it with their camera, iOS and Android can offer to join the network automatically.

The data lives inside the QR itself — it is not a “live” link that we can change after printing. If you change your WiFi password, generate a new QR.

Create one in your browser

1. Open kodotools.com/qr-code-for-wifi (or the WiFi tab on our full generator).
2. Enter your SSID, password, and security type (most networks use WPA/WPA2/WPA3).
3. Download PNG for screens or SVG for sharp print.

With Kodotools, nothing is uploaded: the QR is drawn locally in your browser, which matters when the payload is your WiFi password.

Phones and scanning

• iPhone: Camera app on iOS 11+ usually recognises WiFi QR codes.
• Android: Many devices handle them in the default camera or Google Lens.
• Very old phones may need a dedicated QR app — the QR still works; only the camera software differs.

Practical tips

• Print size: For a poster or wall sticker, use a large QR and high contrast so it scans from a distance.
• Guest networks: If your router supports a guest SSID, put that in the QR instead of your main password.
• Airbnb and cafes: Laminate the print or use a desk stand so the code stays readable.

Where to place the code

Place the QR where guests naturally ask for WiFi: reception desks, cafe counters, meeting rooms, guest bedrooms, or classroom walls. Add the network name beside the QR so people know they are joining the correct WiFi.

For public spaces, avoid putting the QR behind glass glare or in a dark corner. A clean white card with dark QR modules usually scans faster than a decorative sign.

Security note

Anyone who can scan the code can join the network, so use a guest network rather than your private admin or work network. If you change the password, regenerate and reprint the QR.
