Nobody enjoys spelling out a 20-character WiFi password to guests. A WiFi QR code lets anyone scan and connect instantly — no typing, no mistakes. Here's the complete guide to setting one up with QRMax.

How to Create a WiFi QR Code in 3 Steps

Step 1: Gather Your Network Details

You need three pieces of information:


  • Network name (SSID): The WiFi network name as it appears on devices

  • Password: The exact password, case-sensitive

  • Encryption type: WPA/WPA2 (most common), WPA3, or WEP (legacy)


Find these in your router's admin panel or on the sticker on the bottom of your router.

Step 2: Generate the QR Code

  1. Go to QRMax
  2. Select WiFi as the QR code type
  3. Enter your SSID, password, and encryption type
  4. The QR code encodes everything locally — your password is embedded in the code itself, not stored on any server

Step 3: Print and Display

  1. Download the QR code (PNG for framing, SVG for larger prints)
  2. Print and display where guests need it — entryway, kitchen, guest room, lobby
  3. Add a label: "Scan to Connect to WiFi"
  4. Test-scan to verify it connects correctly

WiFi QR Code for Businesses

Cafes and restaurants: Display on table tents alongside your menu QR code. Customers connect without asking staff during the rush. See our restaurant QR guide for more strategies. Hotels and Airbnbs: Include the WiFi QR code in the welcome packet, on the nightstand card, and on the bathroom mirror decal. Guests hate searching for WiFi credentials. See our hotel QR guide. Offices and coworking spaces: Separate QR codes for employee WiFi and guest WiFi. Display the guest code in meeting rooms and the reception area. See our coworking QR guide.

Security Considerations

Use a guest network. Never share your primary network password via QR code. Set up a separate guest network on your router with:
  • A different password from your main network
  • Limited bandwidth allocation
  • No access to local network devices (printers, NAS, etc.)
  • Optional time limits
When you change the password, reprint the QR code. WiFi QR codes are static — the credentials are encoded directly. If you change your WiFi password, the old QR code stops working and you need to generate a new one.

Practical Tips

  1. Frame it nicely — a printed QR code in a small picture frame on the nightstand looks professional and signals to guests that WiFi is available without them having to ask
  2. Include the network name as text — some older devices can't scan WiFi QR codes; printing the SSID and password as text below the QR code ensures everyone can connect
  3. Use a separate guest network — never expose your primary network; most modern routers support guest networks with a few clicks in the admin panel
  4. For printed materials like welcome packets, use MyPDF to create professional-looking PDF guides with the QR code embedded

Do WiFi QR codes work on all phones?

iPhone (iOS 11+) and Android (9+) support WiFi QR codes natively through the camera app. Older devices may need a QR scanner app. Windows and macOS laptops generally can't scan WiFi QR codes without third-party software — include the text password for laptop users.

Is my WiFi password secure in a QR code?

The password is encoded in the QR code data, not stored online. Anyone who scans the code gets the password — that's the point. This is why you should use a guest network with a separate password, not your primary network. Treat the QR code like you'd treat a written-down password.

What happens when I change my WiFi password?

The old QR code stops working because the encoded password no longer matches. Generate a new QR code with the updated credentials and replace the printed version. This is one case where WiFi QR codes must be static — the credentials are embedded directly.
