A WiFi QR code is a special QR code that contains your wireless network's login information. When someone scans it with their smartphone, they can connect to your WiFi network automatically without typing in the password.
This is especially useful when you have a complex password (which you should for security!), guests who speak different languages, or simply want to provide a more modern, convenient experience.
WiFi QR codes use a standardized format that smartphones recognize automatically. The code contains three pieces of information:
The name of your WiFi network as it appears in the list of available networks.
Your WiFi password. It's encoded into the QR pattern - users never see it directly.
The security protocol your network uses (WPA/WPA2/WPA3, WEP, or none).
1. User points camera at QR code
2. Phone recognizes it as a WiFi QR code
3. Notification appears: "Join network [Name]?"
4. User taps to confirm
5. Device connects automatically
Share WiFi with guests without spelling out complex passwords. Frame it near your entrance or living room.
Onboard new employees quickly. Post QR codes in meeting rooms for visitor WiFi access.
Print on table tents or menus. Customers can connect without asking staff for the password.
Include in welcome materials. Guests appreciate the convenience, especially international travelers.
Display on screens or printed materials for easy attendee access to event WiFi.
Provide customer WiFi to encourage longer visits and improve shopping experience.
When creating your WiFi QR code, you'll need to specify the encryption type your network uses. Here's what each option means:
| Encryption | Description | Recommendation |
|---|---|---|
WPA/WPA2/WPA3 | The current standard for secure WiFi. Most home and business networks use this. | Recommended for most users |
WEP | Older, less secure encryption. Rarely used today. | Only if your router requires it |
No Password | Open network without any password protection. | Use only for public guest networks with proper isolation |
Open our generator and choose 'WiFi' from the QR code type options.
Type your WiFi network name exactly as it appears in available networks.
Enter your WiFi password. Make sure it's correct - the QR won't work with typos.
Choose WPA/WPA2 for most networks. Only use WEP or None if your network specifically requires it.
Scan the preview with your phone to verify it connects, then download.
A WiFi QR code contains your wireless network credentials (network name, password, and encryption type). When scanned, it allows devices to automatically connect to the WiFi network without manually typing the password.
Yes, it's as safe as sharing your password any other way. The QR code simply contains the same information you would give verbally. For added security, consider using a separate guest network with limited access.
Yes! Both iOS (iPhone/iPad) and Android devices support WiFi QR codes natively. Just point the camera at the QR code and tap the notification to connect.
You'll need to create a new QR code with the updated password. The old QR code will no longer work because it contains the old credentials encoded in it.
Yes! Our generator supports hidden networks. Simply toggle the "Hidden Network" option when creating your QR code, and the device will know to search for the network even though it's not broadcasting.
