Why Use a WiFi QR Code
Typing a WiFi password from a sign or business card is one of the most frustrating guest experiences. Long passwords with mixed case, numbers, and symbols are easy to mistype. A WiFi QR code solves this completely: the guest points their camera at the code and taps Connect — the entire process takes two seconds.
For businesses, hotels, Airbnb hosts, and coffee shops, a WiFi QR code also means you can change your password occasionally for security without printing new signs. Just regenerate the QR code with the new password and reprint or update the digital display.
QR codes for WiFi are supported natively by iPhone (iOS 11+) and Android (9+) camera apps. No app download is required. The camera app detects the WiFi QR code and shows a Join Network prompt automatically.
- No app required: works with the built-in camera on iPhone and Android
- Faster than typing: guests connect in under 5 seconds
- Professional appearance for cafes, hotels, offices, and event spaces
- Easy to reprint when you change your password
How to Use the WiFi QR Code Generator
Enter your network name exactly as it appears in the WiFi settings on your device. The name is case-sensitive, so make sure capital letters match. Select the security type your router uses: WPA or WPA2 covers almost all modern home and office routers. WEP is for older routers and is not recommended for security reasons.
Enter your WiFi password. Use the Show button to confirm you have entered it correctly before generating the code. If your network is hidden (the SSID is not broadcast), tick the Hidden network checkbox so devices know to connect to a non-broadcast network.
Once the QR code appears, test it with your phone before printing. If it does not connect, the most common cause is a typo in the network name or password. Click Download QR Code PNG to save the image for printing.
Where to Use Your WiFi QR Code
Print the QR code on an A5 card and place it on tables, at reception desks, or near the router. For cafes and restaurants, it works well on table tents or laminated cards. For Airbnb and short-term rentals, include it in the welcome book or print it on a card next to the router.
For offices, display the code on a sign near the entrance or in meeting rooms. Visitors can connect without asking for the password, which saves time and avoids the awkwardness of sharing credentials verbally in meetings.

Frequently Asked Questions
What is a WiFi QR code?
A WiFi QR code encodes your network name, password, and security type in a scannable format. When a smartphone camera scans it, the device automatically joins the network without the user typing anything.
Is it safe to share a WiFi QR code?
A WiFi QR code is as safe as writing your password on a sign. Anyone who scans the code can connect to the network. For guest networks, this is fine. For your main network, consider creating a separate guest WiFi with a simpler password and generating the QR code for that instead.
Does this work on iPhone and Android?
Yes. iPhone running iOS 11 or later and most Android phones running Android 9 or later can scan WiFi QR codes directly with the built-in camera app. No separate app is needed.
What security type should I choose?
Most modern routers use WPA2 or WPA3. Select WPA for either. If your router is more than 10 years old, it may use WEP. If the network has no password, select None. When in doubt, try WPA first.
What if the QR code does not work?
The most common cause is a typo in the network name or password. Both are case-sensitive. Check that the network name matches exactly what appears in your WiFi settings, including spaces and capital letters. Use the Show button to verify the password before generating.
