Create a printable WiFi sign with QR code. Guests scan to connect instantly. Nothing is sent to a server.
This tool creates a printable sign with your WiFi network name (SSID) and password, along with a QR code that guests can scan to connect automatically. When a phone's camera scans a WiFi QR code, the device prompts the user to join the network without manually typing the password. The QR code encodes the network credentials in a standardized format: WIFI:T:WPA;S:NetworkName;P:Password;; (where T is the security type, S is the SSID, and P is the password).
The security type in your QR code must match your router's actual configuration. WPA2 is the most common standard for home networks as of 2025. WPA3 is the newest standard and offers stronger encryption, but older devices may not support it. Some routers use WPA2/WPA3 mixed mode for backward compatibility. If your network is open (no password), the QR code omits the password field and uses T:nopass. Check your router's admin panel or the sticker on the router itself to confirm which security protocol is active.
Print the sign and place it where guests naturally look for connectivity information: near the front door or entryway, in a guest bedroom, in a common area, or at a reception desk. For rental properties and Airbnbs, include the WiFi sign in the welcome binder or frame it near the router. Laminating the sign protects it from wear and makes it easy to wipe clean.
For businesses like cafes, waiting rooms, and co-working spaces, a framed WiFi sign near the entrance or on each table reduces the number of times staff are asked for the password. If you change your WiFi password periodically, generate a new sign each time. The QR Code Generator can create QR codes for other purposes beyond WiFi credentials.
For security, create a separate guest network on your router rather than sharing your main network credentials. Most modern routers support a guest network that provides internet access but isolates guest devices from your personal computers, printers, smart home devices, and network storage. Guest networks can also have bandwidth limits to prevent visitors from consuming your full internet speed. Use the guest network's credentials on the WiFi sign and keep your main network password private.
If a guest scans the QR code and the connection fails, the most common causes are: incorrect security type in the QR code (WPA2 vs. WPA3), a typo in the network name or password, the device being out of WiFi range, or the network being at its device connection limit. Hidden networks (where the SSID is not broadcast) require the hidden=true parameter in the QR code. If your network is hidden, make sure the generator includes this flag. Some older Android devices below version 10 require a third-party QR scanner app because the built-in camera does not process WiFi QR codes natively.
Most routers from major manufacturers (Netgear, TP-Link, ASUS, Linksys, and mesh systems like Eero and Google Wifi) support guest networks through their admin interface or companion app. The guest network creates a separate SSID with its own password that provides internet access but blocks access to devices on the main network. Some routers also allow you to set bandwidth limits on the guest network, schedule it to turn off during certain hours, or set a maximum number of connected devices. These features are especially useful for Airbnb hosts and small businesses that want to offer WiFi without compromising network security.
