WiFi QR Code
Create a QR code that auto-connects phones to your WiFi network.
Eliminating the "What's the WiFi Password?" Friction
Every hospitality venue, shared office, and Airbnb faces the same ritual: a guest arrives, asks for the WiFi password, you spell out "H-u-n-t-e-r-2-dollar-sign-exclamation," they mistype it twice, and the whole process consumes two minutes and mild embarrassment. A WiFi QR code eliminates this entirely. The guest points their phone camera at the printed code and receives a one-tap "Join Network" prompt — no typing, no verbal exchange, no ambiguity about whether that character was a zero or the letter O.
The WiFi QR format is standardized and supported natively by iOS 11+, Android 10+, and modern versions of Windows and macOS. It encodes the SSID, security protocol, and password into a specific text string that device cameras recognize as a WiFi connection request rather than a URL or plain text.
The WiFi QR Format — What Is Actually Encoded
The format is a plain text string with a specific prefix: WIFI:T:WPA;S:NetworkName;P:password123;H:false;; where:
T:is the authentication type: WPA (for WPA, WPA2, and WPA3), WEP (legacy, insecure), or nopass (open network).S:is the SSID. Special characters (backslash, semicolon, comma, quotation mark, colon) must be escaped with a leading backslash.P:is the password. Same escaping rules apply.H:is true if the network is hidden (SSID not broadcast), false otherwise.
This string is encoded into a standard QR code — there is no special magic beyond the format agreement between device vendors. A QR decoder that does not recognize the WiFi format will simply show you the raw WIFI:T:WPA... string.
Security Considerations for Shared WiFi QRs
Posting a WiFi QR is functionally equivalent to writing the password on a whiteboard. The security tradeoffs are identical. Key considerations:
- Use a dedicated guest network: most routers support multiple SSIDs. A guest network isolates visitors from your primary network and from each other. Configure the guest SSID to prohibit inter-device communication (client isolation) and segment it from devices on the main LAN. The WiFi QR should always point to the guest network, not your primary network.
- WPA2/WPA3 vs. WEP: WEP (Wired Equivalent Privacy) was deprecated in 2004 and cracked in 2001. A WEP-protected network can be broken in minutes with widely available tools. If your device only supports WEP, the device needs replacement, not the WiFi standard. Select WPA in this generator for all modern networks; WEP is included only for legacy equipment compatibility.
- QR physical security: unlike a spoken password, a QR can be photographed from a distance by anyone in the venue. Treat the QR as semi-public. For high-security environments, rotate the guest password regularly and regenerate the QR — a process that takes 30 seconds with this tool.
- Hidden networks (SSID not broadcast): hiding the SSID provides minimal security benefit. Passive scanners capture probe requests from devices already connected, revealing the hidden SSID. Hiding adds friction for legitimate users without meaningfully deterring attackers. The hidden option is available in this generator for legacy device compatibility, not as a recommended security measure.
How to Use This Tool
- Enter the WiFi network name (SSID) exactly as it appears in the network settings.
- Select the security type: WPA for modern networks, WEP only for legacy equipment, None for open networks.
- Enter the password (for WPA/WEP networks).
- Check "Hidden network" only if the SSID is not broadcast.
- Download the QR as PNG (for printing) or SVG (for scalable print files).
- Print at minimum 3 cm × 3 cm for reliable scanning at counter distance.
▢ FAQ
01 Will this work on older iPhones and Android devices? +
iOS 11+ (iPhone 6s and later, released 2015) supports WiFi QR natively via the camera app. Android 10+ (2019) supports it natively. Older Android devices running Android 9 or below may need a dedicated WiFi QR scanning app. WPA3 network types require iOS 13+ or Android 10+.
02 Can someone extract my password from the QR? +
Yes — the password is encoded in the QR in plaintext, not encrypted. Anyone who scans or photographs the QR and decodes it with any QR reader (including this site's QR reader tool) gets the full password string. Treat the printed QR with the same confidentiality as a written password. For frequently-visited public spaces, use a guest network with a password you can rotate periodically.
03 My SSID has special characters — does that cause problems? +
Special characters (backslash, semicolon, comma, double-quote, colon) must be escaped in the WiFi QR format. This tool handles escaping automatically — enter your SSID and password as-is and the correct escaped format is generated. If you manually construct WiFi QR strings, escape each special character with a leading backslash: for example, an SSID of Net:Work becomes Net\:Work in the encoded string.
04 Should I use WPA or WPA2 as the security type? +
WPA, WPA2, and WPA3 all use the same "WPA" type code in the WiFi QR format — the format does not distinguish between them. Your device negotiates the highest supported protocol with the router automatically. Select "WPA" in this generator for any modern secured network. The distinction only matters at the router configuration level, not in the QR.
