WiFi QR Code Generator
Generate a scannable QR code for your WiFi network — guests scan it to connect instantly, no typing required.
The password stays on your device, never in the shared link — only the network name and security type are carried in a shared link.
Rendering QR code…
Scan with any modern camera app. QR code never leaves your device.
How WiFi QR codes work
WiFi QR codes encode a standardised string beginning with WIFI:, followed by the security type, SSID, and password. When scanned, Android 10+ and iOS 11+ automatically offer to connect to the network. Special characters in the SSID or password are escaped with a backslash. The QR code is generated in your browser using the qrcode library and is never uploaded.

What this tool is used for
- Letting guests join a network by scanning rather than typing a long passphrase.
- Printing a card for a meeting room or a rental property.
- Sharing a guest network without reading the password aloud.
- Producing a code for a network with a passphrase deliberately too long to type.
- Adding a scannable code beside a printed network name.
Frequently Asked Questions
- What is encoded in the QR code?
- A single line in the `WIFI:` URI scheme — `WIFI:T:WPA;S:MyNetwork;P:password;H:false;;`. It is a plain string with no encryption of its own, so anyone who can photograph the code has the password. That is the point, and also the thing to think about before printing it.
- Why is the password not in the shareable link?
- Because the URL would carry it into browser history, sync, screenshots and every link anyone copies. The SSID and security type are in the link and the password is deliberately not — the same rule already applied to the NTLM hash and password entropy tools.
- What characters need escaping in the SSID or password?
- Backslash, semicolon, comma, quote and colon, each prefixed with a backslash. A password containing a semicolon would otherwise terminate the field and the phone would try to join with a truncated credential — which fails with a generic "incorrect password", giving no hint why.
- Do all phones support scanning it?
- iOS since 11 and Android since 10 handle it in the native camera. Older Androids need a QR app that understands the WIFI scheme rather than treating it as text. Nothing in the format is Apple- or Google-specific — it originated with Android and became a de facto standard.
- Should I use this for a guest network?
- It is the ideal case: a printed code on a guest network with no access to internal resources. On the main network it hands out permanent credentials to anyone who photographs the sign, so pair it with a genuinely separate guest SSID rather than convenience on the primary one.
Common errors and gotchas
- Printing the code somewhere public, which shares the passphrase with anyone who can see it.
- Choosing the wrong security type, which produces a code that fails to connect.
- Forgetting to escape special characters in the passphrase, which breaks the encoded string.
- Assuming every device supports scanning to join, since support varies by platform and version.
- Generating a code for the main network when a guest network was the intention.
