Free WiFi QR Code Generator
Create a QR code your guests can scan to join your WiFi instantly — no password typing needed.
How WiFi QR Codes Work
A WiFi QR code encodes a specially formatted string that smartphones recognize automatically. When the camera app detects this format, it shows a prompt to join the network — no typing required. The string looks like:
WIFI:T:WPA;S:MyNetwork;P:MyPassword;;The fields are: T: (security type), S: (network name), P: (password), and H: (hidden flag). Special characters in the SSID or password — semicolons, colons, backslashes, commas — must be escaped with a backslash. This generator handles all escaping automatically.
Which Devices Support WiFi QR Codes?
iOS 11 and later support WiFi QR codes natively through the Camera app. Android 9 (Pie) and later added native support as well. Older Android versions may need a third-party QR scanner app. In practice, any device from 2018 or newer will handle WiFi QR codes without any extra software.
Popular Uses for WiFi QR Codes
- Restaurants and cafes -- print the QR code on table tents or menus so customers connect instantly.
- Hotels and Airbnb -- place a framed QR code in the room. Guests appreciate not having to ask for the password.
- Offices -- put the QR code on a shared guest network near the reception or conference room.
- Home -- stick a printed QR code on the fridge or near the router. No more dictating passwords to visitors.
Best Practices
The most practical use is printing the QR code and placing it somewhere visible: on the router itself, on the fridge, or in a guest bedroom. A short label like "Scan to connect to WiFi" is all guests need.
Use a guest network password for the QR code rather than your main network password. Most modern routers support a separate guest network that keeps visitors isolated from your personal devices. For an Airbnb or office, print the QR code on a laminated card and use SVG format so it stays sharp at any size.
Change the guest network password occasionally and reprint the code. It takes two minutes and keeps your network tidy.
Security Note
The WiFi password is encoded in plain text inside the QR code. Anyone who scans it can read the password from the QR data. This is expected behavior — the whole point is sharing access. Use a guest network password you are comfortable with guests knowing, not your primary network credentials. Do not post WiFi QR codes publicly unless you intend for anyone to connect.
Frequently Asked Questions
What phones can scan WiFi QR codes?
iOS 11+ and Android 9+ support WiFi QR codes natively through the built-in camera app. Just open the camera, point it at the code, and tap the notification to connect. No third-party app is needed on modern devices.
Is my WiFi password safe?
Yes. This generator runs entirely in your browser — your password is never sent to any server. The QR code is generated locally using JavaScript. That said, the password is encoded in the QR code itself, so anyone who scans the code can read it. Use a guest network password you are comfortable sharing.
What security type should I choose?
Choose WPA/WPA2 for any modern router (this is by far the most common). Select WEP only if your router is very old and only supports WEP. Choose None for open networks with no password. If in doubt, try WPA/WPA2 first.
What does 'Hidden Network' mean?
A hidden network does not broadcast its name (SSID). Checking this box adds a flag to the QR code so the phone knows to search for the network by name rather than discovering it through broadcast. Most home and office networks are not hidden, so leave this unchecked unless you specifically configured your router to hide the SSID.
