You know the routine: a guest arrives, asks for the WiFi password, and you spend two minutes trying to remember whether the "o" is a zero and if there's an underscore somewhere. WiFi QR codes eliminate this entirely. Your guest scans the code with their phone camera, taps "Join," and they're connected. No spelling, no typos, no awkwardness.
In this guide, we'll walk through exactly how to create a WiFi QR code using QR Stealth — completely free, with no sign-up and no account required. Your WiFi credentials are processed entirely in your browser and never sent to any server.
What Is a WiFi QR Code?
A WiFi QR code is a standard QR code that contains your network name (SSID), password, and encryption type in a specific format. When someone scans it with their phone (iOS or Android), the device automatically offers to connect to that network. It's been supported natively on iPhones since iOS 11 and on Android since version 10.
The QR code encodes a string that looks like this:
T = encryption type, S = SSID (network name), P = password
You don't need to know any of this — QR Stealth handles the formatting automatically. But it's useful to understand that there's nothing magical or proprietary happening. It's an open standard that works everywhere.
What You'll Need
- Your WiFi network name (SSID) — exactly as it appears on your router
- Your WiFi password
- Your encryption type (almost always WPA/WPA2 — if you're unsure, select WPA2)
- A device with a browser (phone, tablet, or computer)
Step-by-Step: Create Your WiFi QR Code
Go to qrstealth.com. No account, no sign-up, no email required. The generator loads entirely in your browser.
In the QR type selector at the top of the generator, click the "WiFi" tab. You'll see fields for SSID, password, and encryption type.
Type your WiFi network name exactly as it appears (it's case-sensitive). Enter your password. Select your encryption type — for most home and business networks, this is WPA/WPA2. If your network has no password (like some guest networks), select "None."
QR Stealth lets you change colors, dot styles, and even add a logo to the center of your QR code. For a WiFi code you'll print and display at home or at your business, consider matching it to your decor or branding. Just make sure there's enough contrast between the foreground and background colors for scanners to read it.
Click the download button to save your QR code as a PNG or SVG. Print it and place it somewhere visible — near your front door, on the fridge, at the reception desk, or on a table tent at your cafe.
Where to Display Your WiFi QR Code
The best placement depends on your setting:
- Home: Frame it near the entryway, stick it on the fridge, or place it on a side table in the guest room.
- Office: Print it on a small card at reception or in meeting rooms.
- Cafe / Restaurant: Include it on table tents, on the wall near the counter, or printed on receipts.
- Airbnb / Rental: Put it in the welcome guide or frame it on the wall. This alone will save you dozens of guest messages.
- Event venue: Display it on a poster at the entrance or on the event program.
Tips for the Best WiFi QR Code
Use High Contrast Colors
Dark foreground on light background works best. Avoid light-on-light or pastel combinations — phone cameras may struggle to read them, especially in low light.
Print Large Enough
For wall display, print at least 3" x 3" (about 8cm x 8cm). For table tents, 2" x 2" is usually fine since people scan from close range. The general rule: the farther the scan distance, the bigger the code needs to be.
Test Before You Print
Always scan your QR code with your own phone before printing. Make sure it connects to the right network with the right password. QR Stealth generates a preview you can test immediately.
Update When You Change Your Password
If you change your WiFi password, you'll need to generate a new QR code. The old one will stop working since QR codes are static — the password is baked into the code itself.
Frequently Asked Questions
Does this work on iPhones?
Yes. iPhones running iOS 11 or later can scan WiFi QR codes using the built-in camera app. A notification pops up asking if you'd like to join the network.
Does this work on Android?
Yes. Android phones running version 10+ support WiFi QR codes natively through the camera app or Google Lens. Older versions may need a QR scanner app.
Can someone steal my WiFi password from the QR code?
Technically, the password is encoded in the QR code, so anyone who scans it can extract the password. Treat it like you'd treat a written-down password — display it in appropriate locations and don't share the code publicly if you want to keep the network private.
What encryption types are supported?
QR Stealth supports WPA/WPA2 (the most common), WEP (older, less secure), and open/no-password networks. If your router uses WPA3, select WPA2 — most devices handle this correctly.
Why Use QR Stealth for WiFi Codes?
There are many QR generators out there, but most either require an account, add watermarks, or process your data on their servers. QR Stealth is different:
- No sign-up required — just open the page and start generating
- Your data stays in your browser — WiFi credentials are never uploaded
- Custom designs — colors, dot styles, and logo embedding
- PNG and SVG export — high-resolution output for print
- Completely free — the site is ad-supported, not paywalled
