How to Create a Wi-Fi QR Code for Guests
A Wi-Fi QR code lets guests connect to your network by scanning — no password typing needed. This guide shows you how to create one for your home, business, or venue.
What is a Wi-Fi QR code?
A Wi-Fi QR code encodes your network name (SSID), password, and encryption type into a scannable code. When someone scans it with their phone camera, they are prompted to connect to the network automatically.
Step 1: Gather your network details
You need three pieces of information: your network name (SSID — exactly as it appears in Wi-Fi settings), your password, and the encryption type (usually WPA/WPA2 for modern networks).
Tips
- Check your router settings or sticker for the exact SSID
- WPA2 is the most common encryption type for home and business networks
Step 2: Generate the QR code
Open EZQR, select the Wi-Fi content type, and enter your SSID, password, and encryption type. Customize the design with your brand colors if desired. The QR code is generated instantly in your browser.
Step 3: Print and display
Download your Wi-Fi QR code as PNG, SVG, or PDF and print it. Place it where guests can easily see and scan it — reception desks, table tents, room cards, or wall-mounted signs.
Tips
- Print at minimum 3 cm x 3 cm for easy scanning
- Add "Scan to connect to Wi-Fi" text near the code
Device compatibility
Wi-Fi QR codes work natively on iPhones (iOS 11+) and all modern Android devices. Users simply point their camera at the code and tap the notification to connect. No special app is needed.
Security considerations
The Wi-Fi password is encoded in the QR code pattern. While it is not displayed on screen when scanned, anyone with a QR code reader app could extract the raw data. For sensitive networks, consider using a guest network with a separate password.
Tips
- Use a dedicated guest network for public QR codes
- Change the password periodically and regenerate the QR code
Quick Tips
- Use WPA2 or WPA3 encryption for security
- Create a separate guest network for public Wi-Fi QR codes
- Update the QR code whenever you change the Wi-Fi password
- Print large enough for easy scanning (minimum 3 cm)
- Test on both iPhone and Android before deploying
- Place in visible, well-lit locations
Frequently Asked Questions
Do guests need an app to scan the Wi-Fi QR code?
No. Modern iPhones and Android phones scan Wi-Fi QR codes natively through the camera app.
Is the Wi-Fi password visible when scanning?
No. The password is transmitted directly to the device Wi-Fi settings without being displayed on screen.
What if I change my Wi-Fi password?
You need to generate a new QR code with the updated password. The old code will no longer work.
Can I use this for a hidden network?
Yes. Include the hidden flag when generating the QR code, and the device will connect even if the network is not broadcasting.
