How to Create a WiFi QR Code
Sharing your WiFi password no longer means spelling out a complex string of characters. With a WiFi QR code, guests can connect to your network instantly by scanning a code with their smartphone camera — no typing required.
What Is a WiFi QR Code?
A WiFi QR code encodes your network credentials (network name, password, and encryption type) into a scannable format. When someone scans it, their phone automatically:
- Reads the network name (SSID)
- Reads the password
- Prompts the user to connect (or connects automatically on some devices)
The entire process takes about 2 seconds — compared to the typical 30–60 seconds of manually entering a password.
WiFi QR Code Format
Behind the scenes, a WiFi QR code encodes a string in this format:
WIFI:T:WPA;S:MyNetworkName;P:MyPassword;;Where:
T= Security type (WPA, WEP, or nopass)S= SSID (network name)P= PasswordH= Hidden network (true/false, optional)
You do not need to know this format — QR code generators like QRCode0 handle it automatically.
Step-by-Step: Create a WiFi QR Code
Step 1: Gather Your Network Information
You need three pieces of information:
- Network name (SSID) — The name that appears in WiFi settings
- Password — Your WiFi password (case-sensitive)
- Security type — Usually WPA/WPA2 (most common), WPA3, WEP (legacy), or None
How to find your security type:
- iPhone: Settings → WiFi → tap the (i) icon next to your network
- Android: Settings → Network & Internet → WiFi → tap your network
- Windows: Settings → Network & Internet → WiFi → Properties
- Mac: Hold Option + click WiFi icon in menu bar
Most modern networks use WPA2 or WPA3. If unsure, select WPA/WPA2.
Step 2: Generate the QR Code
- Go to QRCode0
- Select the WiFi QR code type
- Enter your network name (SSID)
- Enter your password
- Select your encryption type
- Check "Hidden network" if your SSID is not broadcast
- Click Generate
Step 3: Customize (Optional)
- Choose colors that match your space or brand
- Adjust the size for your intended display location
- Add a frame with "Scan to Connect" text
Step 4: Download and Display
- For print: Download as SVG or high-resolution PNG
- For digital display: Download as PNG
- Place where guests can easily scan it

Security Considerations
What WiFi QR Codes Expose
A WiFi QR code contains your password in plain text (encoded, but not encrypted). Anyone who scans it gets full access to your network. Keep these security practices in mind:
Recommended Security Practices
- Use a guest network — Create a separate WiFi network for guests that is isolated from your main network and devices
- Change the guest password regularly — Update the QR code when you change the password (easy with QRCode0)
- Limit bandwidth — Configure your router to limit guest network bandwidth
- Set a guest network schedule — Disable the guest network during off-hours
- Do not share your main network — Always use a dedicated guest network for QR code sharing
Guest Network Setup
Most modern routers support guest networks. Here is how to set one up:
- Access your router settings (usually at 192.168.1.1 or 192.168.0.1)
- Find the Guest Network section (under WiFi or Wireless settings)
- Enable the guest network and set a name and password
- Enable client isolation — Prevents guests from seeing other devices on the network
- Set bandwidth limits — Prevents guests from using all your bandwidth
- Create your WiFi QR code using the guest network credentials
Device Compatibility
Devices That Support WiFi QR Codes
| Device | Support | How to Scan |
|---|---|---|
| iPhone (iOS 11+) | Full support | Camera app |
| Android (10+) | Full support | Camera app |
| Android (older) | Varies | May need QR reader app |
| iPad | Full support | Camera app |

What Happens When Someone Scans
On iPhone (iOS 11+):
- Open the Camera app
- Point at the QR code
- Tap the WiFi notification that appears
- Phone connects automatically
On Android (10+):
- Open the Camera app
- Point at the QR code
- Tap the WiFi prompt
- Phone connects automatically
On older Android:
- Download a QR code scanner app (Google Lens works well)
- Scan the QR code
- Follow the connection prompt
Troubleshooting
QR Code Does Not Connect
- Double-check the password — WiFi passwords are case-sensitive
- Verify the security type — WPA2 is the most common; WEP is outdated
- Check for special characters — Some QR generators handle special characters differently
- Ensure the network is visible — If hidden, make sure the "Hidden" option is enabled in the QR code
QR Code Scans But Shows Garbled Text
- The QR code may have been generated incorrectly
- Regenerate using a reliable tool like QRCode0
- Make sure the QR code is in good condition (not damaged or blurry)
Phone Does Not Recognize the QR Code
- Ensure the phone camera has QR code scanning enabled in settings
- Try using Google Lens or a dedicated QR scanner app
- Make sure the QR code is large enough and has good contrast
- Clean the camera lens
Tips for the Best WiFi QR Code
- Use a strong, memorable guest password — Something secure but not impossible to type as a backup
- Include a text label — Print "WiFi Password: [password]" near the QR code for devices that cannot scan
- Laminate for durability — Especially in restaurants, hotels, and outdoor locations
- Update regularly — Change the password monthly and reprint the QR code
- Use the right size — At least 3 cm for table cards, 5 cm for wall displays
