How to Share Your Wi-Fi Password with a QR Code

Typing out a long, random Wi-Fi password for every visitor gets old fast — and it's easy to mistype a mix of upper and lowercase letters and symbols. A Wi-Fi QR code solves this: guests scan it with their phone camera and connect automatically, no typing required.

How a Wi-Fi QR code works

A regular QR code just stores text. A Wi-Fi QR code stores that text in a specific format your phone's camera recognizes — the network name (SSID), the password, and the security type (like WPA/WPA2). When a phone scans it, the camera app reads that structured text and offers to join the network directly, instead of opening it as a link.

What you need before you start

Your network name (SSID), exactly as it appears in your Wi-Fi settings.
Your Wi-Fi password.
The security type — almost all home and business routers today use WPA/WPA2.

How to create a Wi-Fi QR code, step by step

Open the QR Code Generator and choose the Wi-Fi content type.
Enter your network name and password exactly as they appear on your router.
Select the correct security type (WPA/WPA2 is the default for most networks).
Generate the code and download it as a PNG or SVG.
Print it or display it on a screen near your entrance, router, or reception desk.

Where to put your Wi-Fi QR code

Cafes and restaurants often print it on table tents or receipts. For a home office or short-term rental, a small printed card next to the router works well. Keep it somewhere guests will actually see it, not buried in a drawer.

Common mistakes to avoid

Entering the wrong security type — if guests can't connect, this is the most common cause.
Using an outdated password after changing your Wi-Fi settings; regenerate the code whenever the password changes.
Making the printed code too small — keep it at least 2 x 2 cm so phone cameras can focus on it easily.

FAQ

Does a Wi-Fi QR code expose my password to anyone who scans it? Yes — scanning it reveals the password your phone needs to connect, the same as if you told someone the password directly. Only share it with people you're comfortable giving network access to, and regenerate it if you ever need to revoke access.

Will this work on every phone? Most modern iOS and Android phones support scanning Wi-Fi QR codes directly from the camera app. A few older devices may need a separate QR scanner app instead.
