Share Wi-Fi Passwords Using QR Codes on Android

This guide shows you how to turn your Wi-Fi password into a QR code that anyone can scan with their phone camera to join your network instantly—no typing, no typos, no hunting for the password. You’ll learn the built-in Android method, a fallback for older versions, and how to print or share the code. No special apps are required for most phones.

What You’ll Need

• An Android phone connected to the Wi-Fi network you want to share.
• Access to the Wi-Fi settings (you’ll need to be the network owner or have the password).
• A second device (any phone, tablet, or laptop) with a camera to test the QR code.
• Optional: a printer or a messaging app to send the QR code to someone.

Step-by-Step

1. Open Settings. Swipe down from the top of your screen to open the notification shade, then tap the gear icon. Alternatively, find the Settings app in your app drawer.
2. Go to Network & Internet (or Connections). The exact name varies by phone maker—look for “Network & Internet” on stock Android, “Connections” on Samsung, or “Wi-Fi” directly. Tap it.
3. Tap Wi-Fi. You’ll see a list of available networks. Make sure you’re connected to the one you want to share.
4. Open the network details. Tap the gear icon or the “i” (info) icon next to the connected network’s name. On some phones, you may need to tap the network name first, then tap “Details” or a similar option.
5. Find the QR code option. Look for a button that says “Share,” “QR code,” or a QR icon (a square made of smaller squares). On stock Android (Android 10 and later), it’s usually a “Share” button. On Samsung, it’s a QR code icon at the bottom of the network details screen.
6. Authenticate if prompted. Your phone may ask for your PIN, pattern, password, or fingerprint to confirm it’s you. This is a security measure—enter it.
7. View the QR code. The QR code appears on your screen. It contains the network name (SSID) and password encoded, so anyone scanning it can join without typing.
8. Share or save the code. You can:
   • Let the other person scan it directly from your screen.
   • Tap the share icon to send it via WhatsApp, email, or any app.
   • Take a screenshot to save it and print it later.
9. Have the guest scan it. On the other device, open the camera app and point it at the QR code. A notification will appear—tap it to join the network. On iPhones, this works automatically; on other Androids, you may need to tap the notification.

If your Android version doesn’t have a built-in QR option (pre-Android 10 or some custom skins), you can use a third-party app:

10. Install a QR generator app from the Play Store (search for “Wi-Fi QR code generator”).
11. Open the app, select “Wi-Fi,” enter your network name (SSID) and password, and choose the security type (usually WPA/WPA2).
12. Generate the QR code and share or print it.

Common Mistakes

• Sharing the wrong network: Make sure you’re connected to the network you intend to share. If you’re on a guest network, the QR code will share that, not your main one.
• Typing the SSID wrong in third-party apps: The SSID must match exactly, including uppercase/lowercase letters. A single typo means the QR code won’t work.
• Choosing the wrong security type: Most home networks use WPA/WPA2 or WPA3. If you select the wrong type in a third-party app, the connection will fail.
• Sharing a screenshot that includes other info: If you screenshot the QR code, make sure it doesn’t also show your password in plain text (some phones display it). Crop the image if needed.
• Assuming all QR scanners work: Some older or third-party QR scanner apps may not handle Wi-Fi QR codes. The built-in camera app on modern phones (Android 9+ and iOS 11+) works fine.

Tips

• Print the QR code: Print it on paper and stick it on your fridge or a wall for guests to scan without asking.
• Use a password manager: Some password managers (like Bitwarden or 1Password) can generate Wi-Fi QR codes from saved passwords—handy if you manage multiple networks.
• Test the code yourself: Before sharing, scan it with another device to confirm it works. This catches typos or wrong security types.
• Keep it secure: A QR code is as sensitive as the password itself. Don’t post it publicly (e.g., on social media) unless you want anyone nearby to join your network.
• For guests with iPhones: iPhones can scan Wi-Fi QR codes directly with the camera app—no extra steps needed.

Troubleshooting

• The QR code doesn’t scan: Make sure the screen is bright and the code is fully visible. Clean the screen or increase brightness. If using a printed code, check for smudges or creases.
• The guest scans but can’t connect: The password may be wrong in the code, or the security type is incorrect. Double-check by scanning the code yourself and trying to connect a device that’s not already on the network.
• No QR option in settings: Your phone may be older or running a custom skin that removed it. Use the third-party app method described above.
• The QR code shares the wrong network: You may have been connected to a different network (e.g., a guest network). Disconnect and reconnect to the correct one, then try again.
• The guest’s phone says “Incorrect password”: This usually means the SSID or password in the QR code doesn’t match your router’s settings. If you used a third-party app, re-enter the details carefully. If you used the built-in method, the code is generated from the actual network, so it should be correct—try restarting the router if issues persist.

Frequently Asked Questions

Can I share a Wi-Fi QR code with someone who’s not nearby?

Yes—you can send the QR code image via messaging apps, email, or even post it in a shared document. They can scan it from their screen or a printed copy.

Does the QR code work for hidden networks?

Yes, the QR code includes the SSID, so it will work even if the network is hidden. The guest’s phone will automatically add the network.

Can I use the QR code to share a network that requires a captive portal (like hotel Wi-Fi)?

No—QR codes only work for networks with a simple password (WPA/WPA2/WPA3). Captive portals require a browser login, which QR codes can’t handle.

Is it safe to share my Wi-Fi password this way?

It’s as safe as sharing the password verbally. Anyone with the code can join your network. For guests, consider setting up a guest network with a separate password to keep your main devices more secure.

Will the QR code work on iPhones?

Yes. iPhones running iOS 11 or later can scan Wi-Fi QR codes with the built-in camera app. The phone will prompt to join the network.

Can I revoke access after sharing the QR code?

No—once someone has the QR code (or the password), they can join anytime. To revoke access, you’d need to change your Wi-Fi password, which would invalidate all previously shared QR codes.
