Display Wi-Fi QR Code on Windows: Full Guide

This guide shows you how to turn your Windows PC’s Wi-Fi network into a scannable QR code. Once set up, anyone can join your network by pointing their phone camera at the code — no need to share the password out loud or type it in. You’ll need a Windows 10 or 11 PC that’s already connected to the Wi-Fi network you want to share.

What You’ll Need

• A Windows 10 or 11 computer connected to the Wi-Fi network you want to share.
• Access to a web browser (Edge, Chrome, Firefox, etc.).
• Optional: a QR code scanner app on your phone, though most phones can scan QR codes with the built-in camera app.

Step-by-Step

1. Find your Wi-Fi password. First, you need the exact password of the network you’re connected to. Open Settings (press Windows + I), go to Network & Internet > Wi-Fi, then click on your connected network’s name. Scroll down to Properties and look for View Wi-Fi security key. Click it, and the password will be shown (you may need to authenticate with an admin password or PIN).
2. Copy the password. Select the password text and copy it to your clipboard (Ctrl+C).
3. Open a QR code generator website. In your browser, go to a reputable QR code generator that supports Wi-Fi codes. Some reliable options include QRCode Monkey, QR Code Generator (the one by the QR Code Generator GmbH), or the free tool at qr-code-generator.com. Avoid sites that require an account or payment for basic Wi-Fi QR codes.
4. Choose the Wi-Fi option. On the generator site, look for a menu or button labeled “Wi-Fi” or “WiFi” (it’s usually under “QR Code Type” or “Content Type”). Click it.
5. Enter your network details. You’ll see fields for:
   • SSID (network name) – type the exact name of your Wi-Fi network.
   • Password – paste the password you copied in step 2.
   • Encryption – select WPA/WPA2/WPA3 (or “WPA” if that’s the only option). If your network is open (no password), choose “None”.
   • Some generators also ask for “Hidden” – leave that unchecked unless your network is hidden.
6. Generate the QR code. Click the “Generate” or “Create” button. The site will display a QR code.
7. Download or save the QR code. Look for a “Download” or “Save” button. Save the image as a PNG or SVG file to your computer. If you want to print it, save it as a high-resolution PNG.
8. Test the QR code. Open the saved image on your screen, or print it out. Use your phone’s camera app to scan it. On most phones, the camera will recognize the QR code and show a notification like “Join network” or “Connect to Wi-Fi”. Tap it, and your phone should join the network automatically.
9. Share it. You can now display the QR code on your phone, print it for your office, or embed it in a document. Anyone who scans it will be able to join your Wi-Fi without asking for the password.

Common Mistakes

• Typing the SSID wrong. The SSID must match exactly, including capitalization and spaces. If you type “MyNetwork” but the actual name is “myNetwork”, the QR code won’t work.
• Choosing the wrong encryption type. If you select “WEP” when your router uses WPA2, the QR code will fail. Most modern routers use WPA2 or WPA3. If you’re unsure, check your router’s settings page.
• Including extra spaces in the password. When copying the password, make sure you don’t accidentally copy a leading or trailing space. This is a common issue when copying from Windows.
• Using a generator that adds a logo or tracking. Some free QR generators add a small logo or redirect link that can break the Wi-Fi function. Stick to well-known generators that let you download a clean QR code.
• Forgetting to test the code. Always test the QR code with a different device before printing it out. A typo in the password will only be discovered when someone tries to connect.

Tips

• Use a high-resolution download. If you plan to print the QR code, choose a PNG with at least 1024×1024 pixels. A blurry QR code may not scan.
• Keep a copy of the password. The QR code is only as good as the password it contains. If you change your Wi-Fi password, you’ll need to generate a new QR code.
• Add a label. When printing, add a small text label like “Scan to join our Wi-Fi” so guests know what the code is for.
• Use a dynamic QR code (optional). Some generators offer “dynamic” QR codes that let you change the password without changing the printed code. These usually require an account and may have a subscription fee. For most home users, a static code is fine.
• Secure your QR code. Only share the QR code with people you trust. Anyone who scans it can join your network, which gives them access to your local network and potentially your devices.

Troubleshooting

• QR code doesn’t scan. First, make sure the QR code is displayed clearly and not distorted. If you’re viewing it on a screen, increase the brightness. If you’re printing, use a high-quality printer and ensure the code is large enough (at least 2×2 inches).
• Phone scans but doesn’t connect. Check the SSID and password again. The most common issue is a typo in the SSID or password. Also, verify that the encryption type matches your router’s setting. If your router uses WPA3, make sure you selected that option in the generator.
• Phone says “Network not found”. This usually means the SSID is wrong. Double-check the exact network name, including any special characters. If your network is hidden, you’ll need to check the “Hidden” option in the generator.
• QR code generator site is not working. Try a different generator. Some sites have pop-ups or require JavaScript. If one fails, another will work.
• Can’t find the Wi-Fi password in Windows. If you don’t see “View Wi-Fi security key”, you may not be an administrator on that PC. Try right-clicking the network name and selecting “View connection properties”, or contact your system administrator.

Frequently Asked Questions

Can I create a Wi-Fi QR code without a third-party website?

Windows does not have a built-in tool to generate Wi-Fi QR codes. You can use a PowerShell script or a third-party app, but the easiest way is still a website. If you prefer offline, you can use a free open-source tool like “WiFi QR Code Generator” from the Microsoft Store, but be cautious about the app’s permissions.

Does the QR code work for any device?

Yes, as long as the device has a camera and a QR code scanner. Most modern smartphones (iPhone and Android) can scan QR codes directly from the camera app. The code will trigger the device to connect to the Wi-Fi network automatically.

What if my Wi-Fi network is open (no password)?

In the QR code generator, select “None” as the encryption type. You only need to enter the SSID. The QR code will still work.

Can I change the Wi-Fi password later without changing the QR code?

No, the QR code contains the password. If you change the password, you must generate a new QR code. However, some dynamic QR code services allow you to update the password behind the same QR code, but those are not free and require an account.

Is it safe to share my Wi-Fi QR code publicly?

It’s generally safe to share with guests, but remember that anyone with the code can join your network. If you have sensitive devices on your network, consider setting up a guest network with a separate password and QR code.

Why does my phone ask for a password after scanning?

This can happen if the QR code is not formatted correctly. Make sure you used a generator that supports Wi-Fi QR codes, and double-check the encryption type. Some older phones may not support WPA3, so if your router uses WPA3, try switching to WPA2/WPA3 mixed mode.
