How to Create a QR Code for Your WiFi Password

Q: What about Android phones?

Android 10 and later scan WiFi QR codes natively through the camera app. Older versions can use Google Lens or any QR code scanner app.

Every time a guest visits your home or a customer walks into your cafe, the same conversation happens: "What's the WiFi password?" Then you spell out a long, complex password while they fumble with their phone keyboard, mistype it twice, and ask you to repeat it.

There is a better way. A WiFi QR code lets anyone scan a small image with their phone camera and connect to your network instantly — no typing, no spelling, no frustration. This guide shows you how to create one in under a minute using PDFFlare's free QR Code Generator.

How WiFi QR Codes Work

A WiFi QR code encodes three pieces of information in a standard format that phones recognize automatically:

Network name (SSID): The name of your WiFi network
Password: Your WiFi password
Encryption type: WPA/WPA2 (most common), WPA3, or WEP

When someone scans the code, their phone reads this data and offers to connect to the network with one tap. No manual entry needed. Both iPhone (iOS 11+) and Android (9+) support WiFi QR codes natively through their built-in camera apps.

How to Create a WiFi QR Code: Step-by-Step

Step 1: Find Your WiFi Details

You need three things before starting:

Network name (SSID): The exact name that appears in the WiFi list on your devices. It is case-sensitive.
Password: Your WiFi password, exactly as configured on your router.
Security type: Almost all modern routers use WPA2 or WPA3. If unsure, check your router settings or try WPA2 — it works for the vast majority of networks.

Step 2: Open the QR Code Generator

Go to PDFFlare's QR Code Generator. No account or app needed.

Step 3: Enter WiFi Details

Enter your WiFi credentials in the text field using this format:

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

Replace YourNetworkName with your actual SSID and YourPassword with your actual password. If your network uses WPA3, change WPA to SAE. For open networks (no password), use: WIFI:T:nopass;S:YourNetworkName;;

Step 4: Download and Print

The QR code generates instantly. Download the PNG image. Print it and place it somewhere visible — near your router, on the fridge, at the reception desk, or on a table tent in your cafe.

Where to Display Your WiFi QR Code

Home: Print and frame it near your front door or on the fridge. Guests scan it on arrival.
Cafe or restaurant: Print on table tents, menus, or a small sign at the counter. No more staff interruptions for WiFi passwords.
Office: Display in meeting rooms, reception areas, and conference spaces. New visitors connect without bothering IT.
Airbnb or rental: Include in your welcome packet or frame it in the living room. One fewer question from guests.
Retail store: Display near the checkout or entrance so customers can browse your website on fast WiFi.

Security Considerations

Sharing your WiFi password via QR code is as secure as writing it on a piece of paper — anyone who can see the code can connect. Here are some tips to stay safe:

Use a guest network: Most modern routers support a separate guest network that isolates visitors from your main devices. Create the QR code for the guest network, not your primary one.
Change passwords periodically: For businesses, rotate the WiFi password monthly and print a new QR code. This prevents former visitors from having permanent access.
Do not post publicly: If you display a QR code outdoors or in a window, anyone passing by can scan it. Keep it inside where only intended guests can access it.
Use WPA3 if available: WPA3 provides stronger encryption than WPA2. If your router supports it, use it.

Common Questions

Does the QR code stop working if I change my WiFi password?

Yes. The password is encoded in the QR code at generation time. If you change your WiFi password, you need to generate and print a new QR code.

Can iPhones scan WiFi QR codes?

Yes. Any iPhone running iOS 11 or later (2017+) can scan WiFi QR codes using the built-in camera app. A prompt appears asking if you want to join the network — tap it and you are connected.

What about Android phones?

Android phones running Android 10 or later scan WiFi QR codes natively through the camera app. Older Android versions can use Google Lens or any QR code scanner app.

Can I include the QR code in a PDF?

Absolutely. Download the QR code image and insert it into any document — a welcome guide, a menu, or a flyer. You can even convert it to a PDF using PDFFlare's JPG to PDF tool.
