Unlocking Marketing Potential: Core Functions within Your Portal

When Access Becomes a Challenge: Resolving Login Obstacles

⚠️ Cannot log in with email and password

Cause: Incorrect credentials or forgotten password.

Solution: First, double-check your email address and password for typos. If you still can't log in, try the 'パスワードをリセット' (Reset password) link on the login page to set a new password. Ensure your email is registered to your LINE Business ID or personal LINE account.

⚠️ Login page is blocked or not loading

Cause: Network restrictions or browser incompatibility.

Solution: We know being locked out is stressful. First, clear your browser's cache and cookies. If the issue persists, try accessing the portal using a different web browser (e.g., Chrome, Safari, Edge) or from a different network connection. Corporate firewalls or security software can sometimes interfere with access.

⚠️ LINE app login (QR code) not working

Cause: Issues with QR code scanning or app authentication.

Solution: Ensure your LINE app on your smartphone is updated to the latest version. Make sure your phone's camera can clearly scan the QR code on your PC screen. If the QR code doesn't work, try the email login option within the LINE account login method.
