1. Enter your email address and password on a notepad app. Make sure that:
• There are no extra spaces.
• Everything was entered in half-width characters.
• The characters were entered correctly (letters are case sensitive).
2. Copy the email address and password you entered on the notepad app.
3. Start LINE for Windows, paste your email address and password into their respective fields, then log in.
After entering your password, click the eye icon and check that it was entered correctly.
If you've tried the method above but are still experiencing an issue, it's possible that the login information you entered is different from the information registered to your LINE account.
