Keeping your account safe

Your “identity ” on LINE

Your account is your “online identity ” on LINE. You will not be able to use LINE if you lose your login password or delete your account by mistake. Here is some basic information on how to keep your account safe.

About LINE accounts

How your account works

You must have an account to use LINE

Your account is your “online identity” on LINE, created uniquely for a phone number registered at the time of signing up.
Your account allows you to set a name and profile picture and other items, and choose how you want to be viewed by others on LINE. Information such as who you are connected to on LINE and which stickers you have purchased is also connected to the account. An account is necessary to communicate and use services such as stickers, games, and music streaming (Japan only) on LINE.

Keeping your registration information updated

What to do when changing your phone number

If your phone number has changed, you need to update the phone number information you have registered on LINE. The phone number which is no longer used will usually be taken by another person after a certain period. If that person creates a LINE account with your former number, your account will become unavailable. This is because LINE allows only one account per phone number in order to prevent fraudulent creation and use of LINE accounts.

Deleting the app

Your account remains even when you delete the app

When you delete the LINE app from your smartphone or PC, the chat history on the device will be deleted. However, even if you delete the app, your LINE account remains, with information such as your friends list and purchased stickers attached to it. If you delete the app by mistake, re-install the app and log in to your account again. If you create a new account with the same phone number, your original account will be deleted (including your friends list and purchased stickers).

Your profile information represents you

Choose carefully which information to share

LINE is a tool to communicate with family and friends. To allow other users to recognize who you are on LINE, the name you have set, your profile picture and status message will be visible to them.
You can also choose to set and share your birthday and waiting music for LINE calls (Japan only). This information is your “face” on LINE. Think carefully about whether you want others to see your information before setting it up.

Protecting your account

Set a secure password

Set a password that others don’t know and cannot guess easily

A password is a “key” that you set to prevent others from using your LINE account. If you give your password to other people, they will be able to use your account. Moreover, if you use the same password as you use for other services, people may be able to use your account using a password leaked from another service. To prevent such a risk, set a password that you don’t use elsewhere. Do not use your birthday or phone number as a password, as they can be easily guessed.
