What is a WiFi QR code?

A WiFi QR code encodes your network name and password in a format that phones can scan to connect automatically, without manually typing the password.

Is it safe to share my WiFi password as a QR code?

This tool generates the QR code entirely in your browser using the standard WIFI: format. Your password is never sent to any server. For best security, generate the code for a guest network so visitors can't access devices on your main network.

Your WiFi Password Stays on Your Machine

When you type your WiFi password into a QR code generator, where does that password go? Most generators send it to a server to render the image. This one does not. The QR code is built entirely in your browser using the standard WIFI:T:WPA;S:YourNetwork;P:YourPassword;; format. No network request is made, no data is stored, and your password never leaves your machine. You can verify this yourself: open your browser's developer tools, switch to the Network tab, and watch. Nothing is sent.

Where to Put Your WiFi QR Code

A QR code sitting on your screen is useful once. A printed one keeps working forever. Here are the places where it makes the biggest difference:

Taped to the router — so you never have to dig for the password yourself
Framed in the guest room — visitors connect without asking, even if you're already asleep
Airbnb welcome sheet — print it on the info card along with check-in instructions and house rules
Laminated on the cafe counter — customers scan instead of interrupting staff during the rush
Conference room setup card — one less thing for IT to handle when clients visit

Security Types Explained

The tool asks you to pick a security type. If you're not sure which one your network uses, open your router's admin page (usually 192.168.1.1 or 192.168.0.1 in a browser) and look under wireless security settings.

WPA2 — The standard for most home and office networks since 2004. If your router was made in the last 15 years and you haven't changed the defaults, you're almost certainly using WPA2. It's solid and widely supported.
WPA3 — The newer protocol with stronger encryption and better protection against brute-force attacks. If your router supports it and your devices are recent enough, use it. Some routers offer a WPA2/WPA3 transitional mode.
WEP — An outdated protocol from the late 1990s. It can be cracked in minutes with free tools. If your network still uses WEP, switch to WPA2 immediately — this is a real security risk, not a theoretical one.
Open (None) — No password at all. Only appropriate for networks that are intentionally public, like a coffee shop hotspot behind a captive portal.

Set Up a Guest Network

If you're sharing WiFi with visitors, a guest network is the single best thing you can do for your security. Guest network devices can reach the internet but cannot see or communicate with your main devices — your NAS, your printer, your smart home gear all stay invisible. Most routers made in the last five to ten years support this. Check your router's admin page for a "Guest Network" or "Guest WiFi" option, give it its own name and password, and generate your QR code for that network instead of your primary one. You share access freely without exposing anything on your main network.

What Devices Support WiFi QR Codes?

iPhone: iOS 11 and later — just point the native Camera app at the code
Android: Android 10 and later — use the camera or the WiFi settings QR scanner
Older devices: Use a QR scanner app from the App Store or Play Store
