Is my WiFi password safe?

Your WiFi password is never sent to any server. The QR code is generated entirely in your browser using JavaScript. The password is encoded directly into the QR image on your device. Nothing leaves your browser.

What devices can scan WiFi QR codes?

iPhone and iPad running iOS 11 or later can scan WiFi QR codes using the native Camera app. Android devices running Android 10 or later can scan them using the built-in camera. Older devices may need a dedicated QR scanner app that supports WiFi codes.

How do I print my WiFi QR code?

Download the PNG at 512px size for printing up to 10x10cm at good quality. For larger prints (A4 posters, frames), download the SVG version which scales to any size without pixelation. Print and laminate it for durability.

Q: How does a WiFi QR code work?

A WiFi QR code encodes your network name (SSID), password, and security type in a standard format. When a phone camera scans it, the device automatically prompts to join the network - no typing required. It works on iPhone (iOS 11+) and Android (Android 10+) natively.

How WiFi QR Codes Work

A WiFi QR code stores your network name (SSID), password, and security type in a standard format that Android and iPhone cameras recognize automatically. When someone scans it, their phone prompts them to join the network - no manual typing required. The standard format is: WIFI:T:WPA;S:YourNetworkName;P:YourPassword;; where T is the security type, S is the SSID, and P is the password.

This tool generates the QR code entirely in your browser. Your WiFi password is never sent to any server. The password is encoded directly into the QR code image and exists only in your browser session. Once you download the QR code image, you can delete the browser tab and the password data is gone.

Privacy and Security Considerations

The WiFi password is visible in the QR code to anyone who can decode it using a QR scanner app. Place the QR code only where trusted guests can see it - a table card at your restaurant, a welcome card in your Airbnb, or your home entryway. Do not post the QR code publicly online. Consider using a guest WiFi network (separate from your main network) for QR code sharing, so guests cannot access devices on your primary network. Print and laminate the QR code for durability - most printers produce QR codes that scan reliably for years.

When to Use This QR Code Type

A WiFi QR code is worth making when you are repeating your password out loud several times a day. The obvious case is a cafe or hawker stall: print the code, laminate it, stand it on the table, and customers connect without anyone asking at the counter. It works just as well taped inside a kitchen cupboard for guests, or on a meeting room wall in a small office.

What actually gets encoded is a plain text string holding your network name, the security type, and the password. The scanner reads that string and offers to join the network. It is not encrypted, so anyone who photographs the code can recover the password from it. Treat it like a password written on paper, and use a guest network if that matters.

For printing, the QR standard ISO/IEC 18004 requires a clear margin four modules wide on every side, which Denso Wave documents as the quiet zone. Keep it dark on a light background and print at 2cm square or larger, since anything smaller struggles under cafe lighting.

One thing it cannot do: change the password later. Reprint the code when you rotate it.
