What is a WiFi QR code?
A WiFi QR code is a scannable QR code that contains your WiFi network details: SSID (network name), password, and security type (like WPA/WPA2/WPA3). When someone scans it, their phone prompts them to join the network automatically.
Why it’s useful
Perfect for homes, Airbnbs, offices, cafes, salons, events, and guest networks.
What you need
Your WiFi name (SSID), password, and security type (WPA/WPA2/WPA3 or WEP).
Use InstantQR’s WiFi QR Generator to generate a scannable code in seconds. Then print it or display it on a screen for guests to scan.
Step-by-step: Create a WiFi QR code
Find your WiFi network name (SSID)
Your SSID is the WiFi name you see when connecting. Example: HomeWifi_5G.
Copy your WiFi password
Make sure it’s exact (WiFi passwords are case-sensitive).
Choose the security type
Most networks use WPA/WPA2/WPA3. Older networks may use WEP. If your network is open (no password), choose None.
Generate the QR code
Open wifi-qr-code-generator.html, enter SSID + password, then generate and download the QR code.
Test it before sharing
Scan it with another phone (or ask a friend) to confirm it connects instantly.
If the QR code fails, it’s usually because the SSID or password was typed incorrectly, or the security type was selected wrong. Double-check spelling and capitalization.
How to use a WiFi QR code on iPhone
iPhone can scan WiFi QR codes and join networks quickly. Here’s the typical flow:
- Open the Camera app.
- Point at the QR code.
- Tap the WiFi prompt to join.
If your camera doesn’t detect the code, try scanning from a QR scanner inside another app, or move into better lighting.
How to use a WiFi QR code on Android
Most Android phones can scan WiFi QR codes using the camera or built-in QR scanner:
- Open the Camera (or QR scanner).
- Scan the QR code.
- Tap the connect/join prompt.
Some Android devices also let you create WiFi share QR codes inside WiFi settings, depending on the manufacturer and Android version.
Best way to print & share your WiFi QR code
- Print size: Aim for at least 1.5–2 inches (4–5 cm) wide for reliable scanning.
- High contrast: Dark QR code on a light background scans best.
- Placement: Near entryways, reception desks, coffee counters, or the router.
- Lamination: Great for cafes/Airbnb/hotels to prevent wear.
If you manage multiple locations (Airbnb, office, stores), generate a separate WiFi QR for each network and label it clearly (e.g., “Guest WiFi” vs “Staff WiFi”).
Security tips (recommended)
- Use a guest network if your router supports it.
- Rotate passwords occasionally if many people access your network.
- Avoid posting staff WiFi publicly—use guest WiFi for customers and visitors.
- Use WPA2/WPA3 whenever possible.
