Connecting to Wi-Fi on an Ubuntu laptop without a password
Sharing your Wi-Fi network connection on Ubuntu has never been easier, thanks to the built-in QR code feature. Here's a step-by-step guide on how to generate a Wi-Fi QR code on your Ubuntu laptop and scan it with your phone for instant, password-free access.
On an Ubuntu laptop:
- Open Settings.
- Click on Wi-Fi on the left panel.
- Next to your currently connected Wi-Fi network, you will see a QR Code icon or button—click it. This will display a QR code representing the network credentials.
On your phone:
- Open the camera app or the Wi-Fi settings screen depending on your phone model.
- Use the built-in QR code scanner in the camera or long-press the Wi-Fi icon in the quick settings to bring up the scan option.
- Scan the QR code displayed on your Ubuntu laptop screen.
- Turn on your Wi-Fi on your laptop before scanning the QR code.
- Your phone will automatically connect to the Wi-Fi network without needing to manually input the password.
This method is secure and convenient because the QR code contains an encrypted version of your Wi-Fi credentials, allowing instant connection without password sharing hassles. If your Ubuntu version does not support direct QR code generation in settings, you can generate the QR code via a Python script using the package. However, the built-in method is simpler and requires no coding.
In conclusion, the QR code feature built into Ubuntu allows for easy and convenient Wi-Fi connection. This method keeps your network secure without the need for manual password entry, making it particularly useful when helping guests get online or setting up new devices.
