Guests arrive at your office or Airbnb and ask for the WiFi password. You spell out a 20-character mixed-case password while they mistype it twice. A WiFi QR code solves this — guests point their phone camera at it, tap “Join,” and they’re connected. This tool generates that QR code from your network name and password in seconds.
Why This Tool
WiFi QR codes use a standardized WIFI: URI format that Android and iOS recognize natively. You could manually construct the string and feed it to a generic QR generator, but you’d need to know the exact format and handle special character escaping. This tool does it correctly — pick your encryption type, enter the SSID and password, and download a ready-to-print QR code.
How WiFi QR Codes Work
The QR code encodes a string in the WIFI: format:
WIFI:T:WPA;S:MyNetwork;P:MyPassword;;| Field | Meaning |
|---|---|
T: | Encryption type: WPA, WEP, or nopass |
S: | SSID (network name) |
P: | Password |
H: | Hidden network flag (true/false) |
When a phone camera scans this QR code, the OS parses the string and offers to join the network automatically — no manual typing needed.
Supported Encryption Types
- WPA/WPA2/WPA3: The current standard. Most home and office networks use WPA2 or WPA3. Select “WPA” in this tool.
- WEP: Legacy encryption, considered insecure. Only use if your router doesn’t support WPA.
- Open (no password): For public networks. The QR code contains only the SSID.
Where to Use WiFi QR Codes
- Guest rooms and Airbnb: Print and frame near the router
- Offices: Post in meeting rooms and reception areas
- Cafés and restaurants: Add to table cards or menus
- Events: Display on screens or printed materials
- Home: Stick on the router itself for visitors
Tips for Printing
- Size: Print at least 2×2 cm (about 1 inch) for reliable scanning from phone distance
- Contrast: Black QR on white background scans most reliably
- Label: Add the network name as text below the QR code so people know what they’re scanning
- Laminate: Protect printed codes in high-traffic areas
Frequently Asked Questions
Is it safe to share my WiFi password via QR code? The QR code contains your password in plain text (encoded in the QR pattern). This is as secure as writing the password on a sign — anyone who can see or photograph the QR code can extract the password. Place it where only authorized people can access it.
Which phones can scan WiFi QR codes? All iPhones (iOS 11+) and Android phones (Android 10+) support WiFi QR codes natively through the camera app. Older Android versions may need a third-party QR scanner app.
Does the QR code update if I change my password? No. The QR code is a static image encoding the password at the time of creation. If you change your WiFi password, you need to generate and print a new QR code.
Can I use this for hidden networks? Yes. Enable the “Hidden network” option and the generated QR code will include the hidden flag, so phones will attempt to connect even though the SSID isn’t broadcast.
Does this tool send my password to a server? No. The QR code is generated entirely in your browser using JavaScript. Your network name and password never leave your device.
