How to Make a QR Code for Your WiFi Password (So You Never Have to Spell It Out Again)

Create a QR code that lets guests connect to your WiFi instantly — no typing, no spelling out your password. Works for homes, Airbnbs, restaurants, and offices.

The Problem Everyone Has

Someone comes to your house. They ask for the WiFi password. You say "it's capital B, lowercase r, zero, not the letter O, underscore, seven, seven..." and three attempts later they're still not connected.

Or you run an Airbnb and every single guest messages you asking for the WiFi. Or you manage a café and the barista is spelling out the password 40 times a day.

There's a better way. One QR code. Guests scan it with their phone camera. They're connected. Done.

How WiFi QR Codes Work

A WiFi QR code isn't magic — it encodes a specific text string that phones recognize as a network configuration. The format looks like this:

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

When a phone's camera reads this, it automatically offers to connect to that network with the credentials embedded in the code. No typing required. Works on both iPhone (iOS 11+) and Android.

The three pieces of information encoded are:

  • T — The security type (WPA, WPA2, WEP, or nopass for open networks)
  • S — The SSID (your network name, exactly as it appears)
  • P — The password (case-sensitive, exact match required)

    • Step-by-Step: Create Your WiFi QR Code

    1. Find Your WiFi Details

    You need your exact network name (SSID) and password. These are case-sensitive — "MyWiFi" and "mywifi" are different networks.

    On your router: Check the sticker on the bottom or back. It usually lists the default SSID and password.

    On iPhone: Settings > WiFi > tap the (i) next to your network > tap the password field > authenticate with Face ID.

    On Mac: Open Keychain Access, search for your network name, check "Show password."

    On Windows: Settings > Network & Internet > WiFi > your network > Properties > toggle "Show password."

    On Android: Settings > WiFi > tap your connected network > "Share" button shows a QR code (but read on — we'll make a better one).

    2. Generate the QR Code

    Go to FluidConvert's QR Code Generator and paste this string, replacing the placeholder values with your actual network info:

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

    Example: If your network is called "Smith Family" and the password is "TacoTuesday99", you'd enter:

    `WIFI:T:WPA;S:Smith Family;P:TacoTuesday99;;`

    Click generate. Download the QR code as PNG or SVG.

    Security type notes:

  • Use `WPA` for WPA2 or WPA3 networks (this covers most modern routers)
  • Use `WEP` for older WEP networks (rare these days)
  • Use `nopass` for open networks with no password: `WIFI:T:nopass;S:NetworkName;;`

    • 3. Print It

    Print the QR code and put it where guests can see it:

  • At home: On the fridge, near the router, or framed on the wall
  • Airbnb: In the welcome book, on the nightstand, or printed on a card
  • Restaurant/café: On table tents, near the register, on the menu, or on a wall sign
  • Office: In the conference room, at reception, or on the guest WiFi info sheet

    • A good size is 2-3 inches (5-7 cm) square. Any smaller and older phones might struggle to scan it.

    Tips

    Add a Label

    Don't just print a bare QR code. Add text above or below it:

  • "Scan to connect to WiFi"
  • "Guest WiFi — scan with your camera"

    • People need to know what the code does before they'll scan it.

    Use Your Guest Network

    If your router supports a guest network (most do), set one up and use that for the QR code. This keeps visitors on a separate network from your personal devices. Your smart home gadgets, NAS, and computers stay isolated.

    What If You Change Your Password?

    You'll need to generate a new QR code with the updated password. The old code will stop working immediately since the encoded password no longer matches. If you've printed the old code, you'll need to reprint.

    Special Characters in Passwords

    If your password contains semicolons (;), colons (:), or backslashes (\), you need to escape them with a backslash in the QR string. For example, a password of `pass;word` becomes `pass\;word` in the encoded string.

    Most passwords don't have these characters, but if yours does and the QR code isn't working, this is probably why.

    Does This Work on All Phones?

    iPhone: iOS 11 and later (2017+). Just open the camera app and point it at the code. A notification pops up asking if you want to join the network. Tap it. Done.

    Android: Android 10 and later handles it natively through the camera. Older Android versions may need a QR code scanner app, but most phones sold in the last 5 years work out of the box.

    Laptops: Most laptop cameras and webcam apps don't support WiFi QR codes natively. This is primarily a phone feature.

    Is It Safe?

    The QR code contains your WiFi password in plain text — anyone who scans it can see the password if they decode the QR data. This is no different from writing the password on a sign, which you're effectively doing.

    For a home guest network or a café's public WiFi, this is perfectly fine. For a business network with sensitive data, use a separate guest network with its own password for the QR code, and keep your internal network credentials private.

    Make One Now

    1. Open the QR Code Generator
    2. Paste: `WIFI:T:WPA;S:YourNetwork;P:YourPassword;;`
    3. Download and print

    Thirty seconds of setup saves you from spelling out your password for the rest of time.
