How to Create a WiFi QR Code (Share Your Password Instantly)

Nobody likes typing in WiFi passwords. A WiFi QR code lets guests scan and connect instantly — no asking for the password, no spelling out "xK9#mP2$" letter by letter.

Here's how to create one in about 30 seconds.

How WiFi QR Codes Work

A WiFi QR code encodes three pieces of information:

1. Network name (SSID) — Your WiFi network's name
2. Password — The network password
3. Encryption type — Usually WPA/WPA2 (the standard for modern networks)

When someone scans it with their phone camera, the device automatically offers to join the network. One tap and they're connected.

Important: WiFi QR codes are always static. The WiFi credentials are encoded directly into the QR pattern. This means:

• They work without any internet connection (the phone reads the data locally)
• They work forever (no server dependency)
• If you change your WiFi password, you need to generate a new QR code

Create a WiFi QR Code (3 Steps)

Step 1: Gather Your WiFi Details

You need:

• Network name — The exact name as it appears in your WiFi list (case-sensitive)
• Password — Your WiFi password
• Security type — Almost always WPA/WPA2. If your network is from the last 10 years, it's WPA2. Only select "None" for open networks with no password.

How to find your WiFi password if you forgot it:

• iPhone: Settings → WiFi → tap the (i) next to your network → Password
• Android: Settings → WiFi → tap your network → Share → shows QR code and password
• Mac: Keychain Access → search for your network name
• Windows: Network settings → your network → Properties → Show password
• Router: Check the sticker on the bottom/back of your router

Step 2: Generate the QR Code

1. Go to QRMax's WiFi QR Code Generator
2. Enter your network name exactly as it appears
3. Enter your password
4. Select your security type (WPA/WPA2 for most networks)
5. Click Generate

Step 3: Print or Display

Download the QR code and put it where guests will see it:

• Home: Frame it near your router or entryway
• Office: Print on a small card for the reception desk
• Café/Restaurant: Add to table tents alongside your menu QR code
• Airbnb/Hotel: Include in your welcome packet or frame on the nightstand
• Events: Display on signage at the venue entrance

Best Placement Ideas

For Your Home

Print the QR code on a small card and put it in a frame. Place it:

• Near the front door
• On the fridge
• In the guest bedroom
• On the coffee table

A simple label saying "Scan to Connect to WiFi" is all you need.

For Your Business

For Events

For conferences, weddings, or parties:

• Include on printed programs
• Display on screens during the event
• Add to table centerpiece cards

Tips for a Better WiFi QR Code

Make It Readable

• Use a minimum size of 2" × 2" for wall/desk display
• Keep high contrast (dark code on light background)
• Leave white space around the code

Add Context

Always include text that tells people what the QR code does:

• "Scan to Connect to WiFi"
• "Guest WiFi — Scan to Join"
• "Free WiFi — Scan Here"

Separate Guest and Private Networks

For businesses, create a separate guest WiFi network rather than sharing your primary network credentials. Most modern routers support guest networks. Then create a QR code for just the guest network.

Update When You Change Passwords

Since WiFi QR codes are static, remember to generate and print a new one whenever you change your WiFi password. A good habit: update the QR code the same day you change the password.

Compatibility

WiFi QR codes work on:

• iPhone — iOS 11+ (2017 and later), built into the camera app
• Android — Most Android 10+ devices, built into the camera app
• Older devices — May need a third-party QR scanner app

The feature is built into the default camera app on all modern smartphones. No special app required.
