QR Code for WiFi

Generate a free WiFi QR code so guests, customers, and employees can connect to your network instantly. No sign up, no limits, no data upload.

What Is a WiFi QR Code?

A WiFi QR code encodes your wireless network credentials — the network name (SSID), password, and security type — into a scannable QR code. When someone scans the code with their smartphone camera, their device automatically connects to your WiFi network without needing to type in a password.

This works natively on iOS (iPhone), Android, and most modern devices. There is no app to download and no extra steps. Just point, scan, and connect.

How WiFi QR Codes Work

A WiFi QR code stores your network details in a standard format that smartphone operating systems recognize. The code contains:

• SSID: The name of your WiFi network.
• Password: The network security key.
• Encryption type: WPA/WPA2, WEP, or open (no password).
• Hidden network flag: Optional indicator if your network is not broadcasting its SSID.

QRBuilt generates the WiFi QR code entirely in your browser. Your network credentials never leave your device — no data is uploaded to any server.

Supported Security Types

• WPA/WPA2 (recommended): The most widely used security protocol for modern routers.
• WEP: An older security standard. Still supported for legacy devices.
• None (Open): For public or guest networks with no password. Use with caution.

Best Use Cases for WiFi QR Codes

How to Create a WiFi QR Code

1. Visit QRBuilt.com — Open the QR code generator in your browser. No sign up required.
2. Click the WiFi tab — Select the WiFi option from the QR type tabs.
3. Enter your network name (SSID) — Type your WiFi network name exactly as it appears.
4. Enter your password — Type your network password. Leave blank for open networks.
5. Choose the security type — Select WPA/WPA2, WEP, or None. Make sure it matches your router settings.
6. Download your QR code — Your WiFi QR code appears instantly. Download as PNG or SVG to print or share.

Printing and Placing Your WiFi QR Code

A WiFi QR code only helps if guests can find and scan it. Print it at a size of at least 2×2 inches (5×5 cm) so the modules stay crisp, and keep a quiet zone of white space around it. Laminate the printout for durability in cafes and hotel rooms, or add the code to your digital welcome packet for Airbnb and vacation-rental guests. Place it where people naturally reach for their phones — at the counter, on the table tent, or beside the check-in desk.

Set Up a Guest Network First

Sharing your main WiFi password via QR code is convenient, but it also grants full network access to anyone who scans. For businesses, the safest pattern is to create a separate guest network with a simple password, then generate the QR code for that guest SSID. Guests get internet access while your internal devices, POS systems, and smart appliances stay isolated. Most modern routers support a guest network in a few clicks under wireless settings.

Troubleshooting: Why Won't It Connect?

• Wrong security type: If the code says WPA/WPA2 but your router uses WEP, the device may fail to connect. Match the type exactly.
• Hidden SSID: If your network does not broadcast its name, enable the hidden-network flag when generating the code.
• Special characters: Passwords with unusual symbols are usually fine, but double-check the encoded password if a connection fails.
• Outdated device: Very old phones may not auto-connect from a QR scan; the password will still be filled in for manual connection.
