Account/Profile issues
Important: Details about phone number registration and verification only apply to LINE accounts created with LINE versions earlier than 13.11.0 if you're not using LINE in Hong Kong, Japan, Korea, Taiwan, or Thailand.
You can only use this feature on your main device (typically your smartphone) with the latest version of LINE installed.
If the following screen saying "You've been logged out of your account" suddenly appeared, it may be for one of the following reasons.
Reasons:
• You haven't registered your currently contracted phone number to LINE
• You entered and verified the same phone number with LINE on another device
• Someone else entered your information (e.g. verification code, phone number, password, account transfer code) on another device
You haven't registered your currently contracted phone number to LINE:
If the phone number you registered to LINE isn't the same as your current phone number (e.g. you canceled your previous phone number and got a new one) you may suddenly be logged out of LINE.
Once a certain amount of time passes after canceling your phone number, someone else can receive a contract for it and use it.
With LINE, the same phone number cannot be registered to multiple LINE accounts. If the new owner of the phone number registers it to LINE, the LINE account previously registered with that number becomes unavailable.

The other person cannot steal your account or access your LINE data (such as your friends or chat history).
To prevent the same situation from occurring in the future, be sure to register your latest phone number to LINE if it changes.
As there is no way to transfer your previous LINE account, we ask that you create a new LINE account with your current phone number.
Depending on the results of our investigation, we may be able to transfer some paid items from your previous account to your new account. If you'd like us to look into your paid items, please contact us via the Inquiry Form.
The following data can be transferred:

You entered and verified the same phone number with LINE on another device:
The same phone number being registered to (verified with) more than one LINE account is causing the issue. With LINE, you can only register (verify) one LINE account with one mobile phone number. If you register (verify) a different LINE account using a phone number that is already registered to another LINE account, your previous LINE account will be automatically deleted.
Since there is no way to transfer your previous account, please continue using the account you currently have access to, or create a new one.
