Important: protecting your account from being stolen toggle
There have been many cases in which unauthorized third parties have logged in to internet services using email addresses and passwords leaked from other services. No information registered to LINE, such as phone numbers, email addresses, and passwords, has been compromised.

If you use the same email address and password for LINE as another service, we strongly recommend changing your password and PIN
(only available in some countries and versions of LINE).

1. Changing Your Password
2. Changing Your PIN

Tips for a Strong PIN
- Do not use the same or consecutive numbers.
- Do not use numbers related to your personal information.

Reported Cases of Unauthorized Logins
The following types of messages are often sent by the third party when an account is stolen. If you receive messages asking you to do the following from a friend, their account may have been stolen.

- Help me buy prepaid cards
- Help me buy iTunes cards
- I’m in trouble and need you to transfer money to my bank account

As they may change the content of their messages at any time, you should also suspect if your friend’s account has been stolen in the following cases.
- The messages don't sound like the way your friend talks
- A friend whom you have not spoken to for a long time suddenly asks you for money
- The friend's language is unnatural

If Your Friend’s Account Has Been Stolen
If you suspect that your friend’s account may have been stolen, please contact them outside of LINE (in person, by text, by phone, or on a social network) to let them know.

If Your Account Has Been Stolen
If you are suddenly unable to access your account even though you did not make any changes to it, or if your friend contacts you to let you know that your account has been stolen, please see the following article.

You can carry over your account with the either of the following three methods.
