How to Create a WiFi QR Code — Share Your WiFi Password Instantly
Create a QR code that connects devices to your WiFi network automatically. Step-by-step guide for home, office, and hospitality.
Instead of spelling out your WiFi password letter by letter, create a QR code that connects devices automatically. One scan, instant connection. Here's how to set it up with QRMax.
Step-by-Step Creation
- Go to QRMax.io and select the WiFi QR type
- Enter your network name (SSID) — exactly as it appears in WiFi settings
- Enter the password — case-sensitive, must match exactly
- Select the security type:
| Security Type | When to Use |
|---|---|
| WPA/WPA2 | Most modern networks (default choice) |
| WPA3 | Newer routers with WPA3 enabled |
| WEP | Legacy networks only — not secure |
| None | Open networks (no password) |
- Check "Hidden network" if your SSID isn't broadcast
- Customize the design — add colors, your logo, a frame saying "Scan for WiFi"
- Download and print — SVG for print, PNG for screens
How WiFi QR Codes Work
The QR code encodes a special WiFi configuration string:
WIFI:T:WPA;S:YourNetworkName;P:YourPassword;H:false;;When scanned, the phone recognizes this format and prompts the user to connect to the network. No app needed — it's built into iOS (11+) and Android (10+).
Where to Display WiFi QR Codes
| Location | Placement | Size |
|---|---|---|
| Home | Printed card near router | 5 cm |
| Office reception | Framed sign at front desk | 8-10 cm |
| Hotel room | Tent card on nightstand | 5-7 cm |
| Restaurant | Table tent or menu footer | 4-5 cm |
| Retail store | Sign near checkout | 6-8 cm |
| Conference room | Wall sign near entrance | 8 cm |
| Airbnb | Welcome guide or fridge magnet | 5-7 cm |
Static vs Dynamic for WiFi
Use static. WiFi QR codes should be static because the phone needs the credentials locally — it doesn't open a URL. Dynamic QR codes redirect through a server, which doesn't work for WiFi authentication.If you need to change the WiFi password regularly, print new static codes each time. For hotels and offices that rotate passwords, consider a guest network with a fixed password and a separate staff network.
Guest Network Best Practices
- Create a dedicated guest network separate from your main network
- Set bandwidth limits to prevent guests from consuming all your bandwidth
- Use a memorable but secure password — at least 12 characters
- Change the password periodically for security, and update the QR code
Does WiFi QR code work on all phones?
iPhone (iOS 11+) and Android (10+) support WiFi QR codes natively. Older devices may need a QR scanner app. Most phones manufactured after 2018 work without issues.
Is sharing WiFi via QR code secure?
The QR code contains your password in plain text within the encoded data. Anyone who scans it sees the password. This is fine for guest networks but don't use it for your primary network unless you trust everyone with access to the QR code.
Can I create a WiFi QR code for a hidden network?
Yes. Check the "Hidden SSID" option when creating the code on QRMax. The encoded string includes a flag that tells the phone to search for the hidden network.
