Checklist to keep your account safe

　1. Is your registered phone number and email address up-to-date?

　If you don't register your phone number correctly, you may not be able to transfer your LINE account to a new device. Furthermore, you may suddenly lose access to your account if you still have your old phone number registered. This will happen if you dispose of an old phone number and it gets assigned to a new customer, the new customer will be able to create her/his own LINE account with your old phone number.

　Also, by registering your current email address, you will be able to reset your password if you are transferring your LINE account to a new device and cannot remember your password.

　　　　Changing your email address: https://help.line.me/line/?lang=en&contentId=20000060

　2. Do you remember your password?

　A password is required for transferring your LINE account to a new device. If you haven't set a password or have forgotten it, you will not be able to transfer your LINE account and all of its data to a new mobile device.

　3. Is your password unique and difficult for someone else to guess?

　Use a strong password that cannot be easily guessed by others to prevent hackers from stealing your account. Also, do not use the same password you're using for another service/platform. Otherwise, hackers may take over your LINE account if the other service/platform suffers a data breach.

　4. Are you using biometric authentication to log into your account?

　You can log into your LINE account on your computer or iPad using biometric data (face and fingerprint, etc.) if you have enrolled them in your smartphone.

Beware of scams that use LINE accounts! What to do if you encounter any of the following situations

　Situation 1 - "A friend has asked me for my phone number and PIN."*1

　A scammer has most likely taken over your friend's account. A PIN is important information used only for creating accounts and authentication, so they should not be shared with anyone, even friends and family. Otherwise, it will cause your account to be compromised.

　*1: A PIN is a four-digit code sent to users via SMS when they register a phone number on their LINE account.

　Situation 2 - "I got an email claiming to be from LINE."

　It is likely a phishing email from a scammer who's posing as LINE. They may be trying to steal your account by asking you to enter your personal details, so avoid clicking on any links in the body of the email. If you open a link by mistake, close the browser immediately. The website is likely to be fake even if it appears to be genuinely from LINE.

　LINE never solicits by email, so if you are prompted to provide your personal details (e.g. phone number, password, email address, and PIN) in an email claiming to be sent from LINE, assume it is a scam.

　Real examples of phishing scams: https://linecorp.com/en/security/article/396

　If you receive a scam email claiming to be from LINE, please report it to dl_pm-report@linecorp.com

　Situation 3 - ”I got a strange message from a friend asking me to buy Webmoney."

　A scammer has most likely taken over your friend's account. As a first rule of thumb, do not reply to the message. If you can contact your friend by other means such as phone or SMS, reach out to your friend and tell them to contact LINE Customer Support. If this is not possible, you can report your friend's account through you and your friend's 1-on-1 chat. 　　

　Reporting chats by tapping and holding the message you want to report: https://help.line.me/line/?lang=en&contentId=20000260

　Situation 4 - "An unknown or suspicious account is sending advertisements (spam) or other unwanted messages to my account."

　Report the account through the 1-on-1 chat screen.

　Reporting chats and content: https://help.line.me/line/?lang=en&contentId=20000298

　Furthermore, you can turn on message filtering to stop receiving messages from people you don't know. From the Home tab, tap Settings > Privacy > Filter messages.

　Situation 5 - "I've gotten a notification for a failed login that I'm not aware of."

　It's possible that your account is being targeted and someone is attempting to log in. Change your password as a safety precaution.

Checking/changing your password: https://help.line.me/line/?lang=en&contentId=20000062

　Situation 6 - "I've gotten a notification for a successful login that I'm not aware of."

　Go to Settings > Account > Devices and check the devices that are logged into your LINE account. If you did not log in on one or more of the listed devices, log out of those devices. 　For extra security, change your password to prevent attackers from logging in again.

安全使用所需的確認要點

　確認①. 您所註冊的電話號碼和電子郵件地址是最新的資料嗎？

　如果未正確註冊電話號碼，在變更設備時，可能無法順利轉移帳號資料。另外，如果註冊資料一直保留已經解約的電話號碼，當您已解約的電話號碼被分配給新用戶且新用戶使用該電話號碼建立新的LINE帳號時，您的帳號就會變成無法使用的狀態。

　此外，如果已經正確註冊電子郵件地址，即使您在轉移LINE帳號至新的設備時忘記密碼，您也可以重設密碼。

　　請參閱此處，以了解如何設定或更改您的電話號碼（https://help.line.me/line/?lang=zh-Hant&contentId=20000120）

　轉移帳號時，一定會用到密碼。如果未設定密碼或是忘記密碼，您將無法轉移LINE帳號及其所有資料至新的設備。

請注意使用LINE帳號的詐騙手法！～遇到這樣的情況時您可以這樣做～

　【狀況1】好友向我詢問電話號碼和簡訊認證碼（※1）

　【狀況2】收到一封郵件，標題註明為「來自LINE的郵件」

　該電子郵件可能是「網路釣魚郵件」，詐騙者試圖冒充LINE，要求您輸入個人資料，以盜用您的帳號。

　請勿開啟郵件中的任何連結網址，如果不小心開啟，請立即關閉瀏覽器。即使有些網站看起來像是真正LINE應用程式的畫面，但它可能只是假冒的網站。

　LINE不會突然透過郵件聯絡您，所以當您被「來自LINE的郵件」要求提供個人資料（如電話號碼、密碼、郵件地址、簡訊認證碼）時，請假設該郵件為詐騙信件，千萬不要輸入任何資料。
