Account compromise/hacking Main

  1. Kakao Accounts are secured.

    However, if you use the same email address and password that you use for other services or websites, that information can be hacked and your Kakao Account can also be threatened.

    In order to protect your Kakao Account,
    please create a unique password that is not easy to guess, and change it regularly.

  2. Check the information below if you suspect someone else has logged in with your Kakao Account or if there is history or notification of login attempts you did not make.

    1. Immediately reset your Kakao Account password.

    If you use the email or password you entered into your Kakao Account in other services, another person may be attempting to compromise your Kakao Account with information they acquired (or were distributed to them) when personal information was leaked from other services. Therefore, you must use a password that has not been used in any other service as your Kakao Account password. We also recommend that you do not use information that can easily be predicted by others (such as a password that is identical to your ID, your date of birth, name or phone number) as your password.

    Reset password


    2. Once you've reset your password, check your login history. 

    Once you have reset your password, check your login history for any suspicious attempts. Any suspicious attempts will be deleted if you log out of all services when you reset your password. Otherwise, records of suspicious login attempts may remain in your login history. Press the logout button if you find any suspicious login attempts.

    Manage login information


    3. Enable 2-step verification to safely use your account.

    Enable 2-step verification for an added layer of protection. You will be required to enter your Kakao Account and password, as well as an additional verification method to log in. We recommend that you use an email that has not been used elsewhere as your additional verification method, in order to protect your information from others.

    Enable 2-step verification


    Security measures are in place once you have completed steps 1 to 3. You can now safely use your Kakao Account. Please submit a report to the Cyber Terror Response Center if you have experienced material damage after the suspicious login attempt.

    Please read the following if the problem is still not resolved using the above methods.

    Contact Customer Service if someone reset the email or contact information connected to your Kakao Account, or if you have followed the directions provided above but are still unable to log into your Kakao Account due to a 2-step verification process that was enabled by someone other than yourself.

    Once an inquiry about a suspected account fraud is submitted, Customer Service will process the report once the user has been verified.

    Inquire about account fraud/hacking attempts

  3. You can report your account as compromised if you suspect that someone else has logged in with your Kakao Account and you are unable to log in and change your password.

    If an account is reported as compromised, our Customer Service can deactivate the compromised account for 7 days after a phone number verification, limiting your and other people's access to the account.
    Please note that you must submit a report within 14 days of the compromise.

    * You need to submit the account compromise report and other required documents to our Customer Service within 7 days of the account deactivation. Otherwise, deactivation will be lifted automatically.
    Please note that we are able to deactivate your account until police investigation of the compromised account is completed only when you submit the account compromise report and other required documents within 7 days of the account deactivation.

    - Required Documents:
    1. Copy of an ID card or equivalent to verify your identity. (The last 7 digits of the resident registration number must be masked.)
    2. Certificate of use agreement for the mobile phone number used at the time of KakaoTalk registration (issued by the mobile service carrier).
    3. Other materials which may be helpful in proving the unauthorized use of your Kakao service account by someone else.

  4. If you received a login notification email and it is an activity you do not recognize, you can click the link in the email and lock your Kakao Account.

    Once your account is locked, it will be disabled temporarily to prevent other people from using your account, and you will be logged out from all services that are active on your Kakao Account.

    Your account will be unlocked once you change your password.

  5. Selling or exchanging your Kakao Account is strictly prohibited by the Terms of Service. 
    If it is determined that you have sold or exchanged your Kakao Account, or made such an attempt, Kakao has a right to limit your use of Kakao services in accordance with Kakao's operations policy. 


    * Note:

    We are seeing many cases of scams and account compromise resulting from the acts of selling or exchanging Kakao Accounts.

    Selling or exchanging your Kakao Account is strictly prohibited, and we can't provide help with any untoward incident arising out of it. Please read the following information.

    1. If the seller changes mind about selling the account or sells the account with a malicious intent, not only the seller's account but also the buyer's can be disabled.

    Selling or exchanging Kakao Account is prohibited. Even if the buyer claims that he or she has paid money or other equivalent to buy the account, the buyer cannot claim ownership of the involved account.
    Please do not purchase someone else's Kakao Account, as both the seller' and the buyer's Kakao Accounts will be disabled in case the seller reports that account as compromised.

    2. Even if the transaction is not completed, your Kakao Account may be compromised in the process.

    Do not disclose, even in part, your Kakao Account email, password, name or phone number to a third party.
    Name and phone number can be used to find user ID and password for email services such as Naver, Daum and Nate.
    People with malicious intents may be able to combine your personal information disclosed during the transation and guess your Kakao Account email address. 
    Please make sure that you do not disclose your personal information even in part, such as the last few digits of your password.


    Do not delete your Kakao Account email even if your counterpart requests it.
    In some websites, when one user deletes his or her email account, another user can sign up right away using the same user ID.
    Your counterpart may trick you into deleting your Kakao Account email so that he or she can sign up for the same email service using your email address and steal your Kakao Account.

    We also recommend strongly against writing posts on account selling or exchange in open online forums.
    Even if you do not disclose your Kakao Account information, your Kakao Account email address can be guessed based on your ID, nickname, membeship number, etc. revealed on online communities, blogs and forums. 

  6. When you log into Kakao Game, Kakao Story, Kakao Talk, etc. using Kakao Account email address and password, login history is sent to you via Kakao Talk or your Kakao Account email address.

    If it is an act you do not recognize, you can protect your Kakao Account by clicking "Change Password" at the bottom of the notification.

  7. It is likely that someone may have accidentally entered your email to create a Kakao Account, or the email address may have been used by another person previously.

    If the Kakao Account is not yours, please click the link at the bottom of the login notification email "Is this NOT your account?" and contact our Customer Service. 

  8. If you use mobile network (3G or LTE) or VPN, the IP location may be different from your login location,
    Please bear this in mind and check once again whether you have a history of logging in on the day you received the login notification. 

    * The IP locations indicated on the website provided by KISA show the location of Internet service providers, and may be different from the actual login locations.
    If you received a Kakao Account Log In Notification and it is an act you do not recognize, please change your Kakao Account password as well as the password for your email account.
    Make sure your Kakao Account password is different from the password for your email account.
