Wi-Fi QR Code: Share Your Password

Turning your Wi-Fi password into a scan code (QR code) lets guests join your network instantly without typing a long passphrase. This guide shows you how to generate a QR code for your Wi-Fi on a phone or computer, and how to make sure it works before you share it. You’ll need your network name (SSID), password, and the security type (usually WPA2 or WPA3).

What You’ll Need

Your Wi-Fi network name (SSID) — exactly as it appears in your device’s Wi-Fi settings.
The Wi-Fi password (case-sensitive).
The security type: WPA/WPA2/WPA3, WEP, or open (no password). If unsure, check your router’s settings page.
A QR code generator — a free website (like QR Code Generator or QRStuff), a phone app, or the built-in option in Windows or macOS.
A phone or tablet with a camera to test the code.

Step-by-Step

Look up your network details. On Windows, go to Settings > Network & Internet > Wi-Fi, click your network, then view the properties. On macOS, open System Settings > Wi-Fi and click Details next to your network. On Android, go to Settings > Network & Internet > Wi-Fi and tap the gear icon. On iPhone, go to Settings > Wi-Fi and tap the info (i) icon. Note the exact SSID and security type.
Choose a QR code generator. For a one-time code, a reputable website works. For a physical print, use a downloadable app (like QR Code Generator for iOS/Android). If you’re on Windows 11, you can use the built-in Wi-Fi QR code feature (see Tips).
Enter your network name (SSID). Type it exactly, including uppercase and lowercase letters. Most generators have a field labeled “SSID” or “Network Name.”
Select the encryption type. Choose WPA/WPA2/WPA3 (or “WPA” if that’s the only option). For older networks, pick WEP. If your network has no password, choose “None” or “Open.”
Enter the password. Type it carefully, matching case exactly. A typo here will make the code fail.
Generate the QR code. Click the button (usually “Generate” or “Create”). The code appears on screen.
Download or print the code. Save the image as a PNG or PDF. For a physical sign, print it on paper or a label. Keep the original image file in case you need to reprint.
Test the code. Open your phone’s camera app (or a QR scanner app) and point it at the code. A notification should pop up, like “Join Wi-Fi network” or “Connect to [SSID].” Tap it, and your phone should connect automatically. If it doesn’t, see Troubleshooting.

Common Mistakes

Wrong SSID case: “MyNetwork” is not the same as “mynetwork.” Copy the exact name from your device’s settings.
Incorrect security type: If you choose WEP when your router uses WPA2, the phone will fail to connect. Check your router’s admin page if unsure.
Password typos: A single wrong character (like a zero vs. the letter O) breaks the code. Double-check by typing the password in a text editor first, then copy-paste.
Using a generic QR code that isn’t Wi-Fi specific: Some generators produce a plain text code that just shows the password as text, not a scannable Wi-Fi credential. Make sure you use a generator that creates a Wi-Fi QR code (the format starts with “WIFI:”).
Not testing the code: A code that looks fine might not work if the generator used the wrong format. Always test with a phone that isn’t already connected.

Tips

Use a high-contrast print: Dark code on a white background scans best. Avoid glossy paper or plastic covers that create glare.
Print multiple sizes: A small code on a keychain might be handy, but a larger one (at least 2×2 inches) is easier to scan from a distance.
Update the code when you change your password: If you change your Wi-Fi password, generate a new QR code. Old codes will stop working.
For Windows 11 users: Go to Settings > Network & Internet > Wi-Fi, click on your network, and select “View Wi-Fi security key.” Then click the “QR code” button to display a scannable code. You can then screenshot or print it.
For iPhone users: iOS 17 and later have a built-in QR code generator for your own network. Go to Settings > Wi-Fi, tap the info (i) icon next to your network, and tap “Share Password” or “QR Code.” This generates a code that others can scan.
Keep the code private: If you share the code publicly (like on a storefront), anyone nearby can join your network. Consider a guest network with limited access.

Troubleshooting

The phone doesn’t recognize the code as a Wi-Fi network. The QR code format might be wrong. Ensure the generator creates a Wi-Fi QR code (the decoded text starts with “WIFI:”). Try a different generator.

The phone scans the code but says “Incorrect password.” The password in the code is wrong. Double-check the case and characters. Try scanning the code with a different phone to rule out a camera issue.

The phone scans the code but says “Network not found.” The SSID is misspelled or the network is hidden. If your network is hidden, you must include the SSID in the code, and the phone must have Wi-Fi enabled. Some phones won’t connect to hidden networks via QR code — consider unhiding the network temporarily.

The code scans but the phone doesn’t auto-connect. Some Android phones require you to tap a notification after scanning. Look for a notification that says “Tap to connect to Wi-Fi” or similar.

The QR code is blurry or distorted. Regenerate the code at a higher resolution (e.g., 1024×1024 pixels) and print it at a larger size. Avoid stretching the image.

The code works on one phone but not another. Older phones may not support WPA3 or the QR format. If you have a mixed environment, consider using WPA2 (if your router allows) or generate a code with WPA2 selected.

Frequently Asked Questions

Can I use a QR code for an open (no password) network?

Yes, but you must select “None” or “Open” as the encryption type. The code will still contain the SSID, so anyone scanning it can join.

Will the QR code work if I change my Wi-Fi password?

No, the code is tied to the password you entered. You’ll need to generate a new code after changing the password.

Can I share the QR code digitally?

Yes, you can send the image via email, text, or display it on a screen. Just make sure the screen brightness is high enough for scanning.

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

It’s as safe as sharing the password itself. Anyone with the code can join your network. If you’re concerned, set up a guest network with a separate password and generate a QR code for that.

Why does my phone ask for a “network name” when scanning?

This usually happens when the QR code contains only the password, not the SSID. Make sure the generator includes the SSID field.

Can I create a QR code for a Wi-Fi network without a password?

Yes, but it’s not recommended for security. If you do, select “None” as the encryption type.
