Method 1: Install the official LINE app for Windows
Steps:
- Download the official LINE Windows app from the LINE website or the Microsoft Store (if available for your region).
- Install the app by running the installer and following the on-screen prompts.
- Open LINE after installation.
- Sign in using your existing LINE account (typically by scanning a QR code with your phone).
- Allow notifications when prompted so you receive messages and calls alerts.
Method 2: Use LINE in a browser (no install)
If you don’t want to install an app, you can use LINE through a browser-based experience (where supported). This is useful for quick access, shared computers, or troubleshooting app issues.
- Open your browser and go to the LINE web entry point.
- Sign in with your LINE account using the QR code method.
- Check browser notification permissions if you want message alerts.
How to sign in safely (QR code)
Most LINE desktop/web sign-ins use a QR code. To keep your account secure:
- Only scan QR codes shown on your own device.
- Make sure you’re on the official LINE site/app.
- If you don’t recognize the sign-in prompt, stop and secure your account.
Common troubleshooting
1) QR code won’t scan or keeps expiring
- Ensure your phone camera is focused and has good lighting.
- Try again after refreshing the QR code in the LINE app.
- Check that both devices are connected to the internet.
2) Notifications not working
- In Windows, confirm notification permissions for LINE.
- In the LINE app settings, verify notification options are enabled.
- Check Windows Focus Assist / Do Not Disturb settings.
3) App won’t open or crashes
- Update LINE to the latest version.
- Restart your PC and try again.
- Temporarily disable VPN/proxy if you use one.
Which option should you choose?
- Best overall experience: Install the official LINE Windows app.
- No installation: Use the browser option (if available).
- Shared or managed devices: Browser mode can be more convenient.
