When You Can't Log In

When you can't log in, the cause is often a typo, your connection, or an account-linking issue. Start by checking the most common causes in order.

Trouble with password login

• Check your email address and password for uppercase/lowercase and full-width/half-width characters
• Use "Forgot password" to receive a reset email
• Check your spam folder too

Trouble with LINE login

• Log in to the LINE app again, then retry
• Remove the authentication link on the LINE side once, then link again

Trouble with biometric or two-factor authentication

• Check your device's biometric authentication settings
• If the two-factor code doesn't arrive, check your SMS / email settings
• If you use an authenticator app, watch out for clock drift

If it still isn't resolved

• Update the app to the latest version
• Restart your device
• Try another device
• Contact support
