QR Code for Your WiFi Password

August 20, 2026

If you’ve ever had a guest over and spelled out Xk9!mP2vQz letter by letter while they squint at their phone, you already know the problem. A WiFi QR code fixes this in one scan: a visitor points their camera at a small printed card, taps a notification, and they’re online. No typing, no typos, no “wait, was that a zero or the letter O?”

How WiFi QR codes actually work

A WiFi QR code isn’t a link to a website — it encodes your network’s credentials directly using a standard format your phone’s camera already understands:

WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;

When a phone camera scans this, it recognizes the WIFI: prefix and offers a native “Join Network” prompt instead of opening a browser. That’s why it works instantly with the stock Camera app on iOS and Android — no third-party scanner required.

Creating one in under a minute

Open the QR code generator and choose the WiFi option.
Enter your network name (SSID) exactly as it appears in your WiFi settings — it’s case-sensitive.
Enter your password and select your security type (almost always WPA/WPA2 for home and business routers).
Download the code as a PNG or SVG and print it, or display it on a screen.

That’s the whole process. It’s free, doesn’t require an account, and nothing about your network leaves your browser during generation — the QR code is generated locally, unlike some tools that route your password through a server.

Where WiFi QR codes are genuinely useful

Airbnbs and rentals — tape one to the fridge or a welcome binder so guests connect without a text message exchange.
Cafes and restaurants — print one on a table tent or receipt so customers don’t have to ask staff.
Offices — a code near reception saves visitors from digging through a guest-network spreadsheet.
Waiting rooms — clinics and salons can offer WiFi without a staff member repeating the password all day.

A few things to double-check before you print

Test it before printing 200 copies. Scan it yourself with both an iPhone and an Android phone if you can — camera QR support has been standard since iOS 11 and Android 8, but it’s worth confirming on your specific devices.
Changing your password later breaks the code. A WiFi QR code is static — it encodes the password at the moment you generate it. If you rotate your password periodically, you’ll need to regenerate and reprint. For codes you expect to update without reprinting, look into a dynamic/redirect-based code instead — see our guide on static vs dynamic QR codes.
Hidden networks need an extra flag. If your SSID is set to hidden, the WiFi QR standard supports an H:true field — most generators, including this one, handle that automatically when you mark the network as hidden.
