If you suspect that someone has logged on to your PC using your Kakao account, you can take the following steps: 


1) When a user logs on to the PC version, an alert message is sent to the mobile device. Therefore, you can immediately find out if someone is using your Kakao account. 


2) Go to More > Settings > Personal > PC Version and tap [Remote Log-out] or [Deregister PC]. 


3) Change the e-mail address or password of your Kakao account. 


If you wish to investigate further into a possible ID theft, report to a nearby police station or cyber police. Please bear in mind that you must maintain your KakaoTalk membership when you file a report. If you were not specifically harmed, there may be limitations in conducting the investigation. Since KakaoTalk does not have investigation rights, we are unable to help with issues related to account thefts. 

However, we will actively cooperate with police upon request by providing necessary information related to the investigation. 

The log-in process in the PC version consists of two steps. You are experiencing this problem because you completed the first step, but failed to complete the second step. 

Once the first step is completed successfully, a log-in alert is sent to your mobile device. However, you may still fail to complete the second step because network administrators at banks, government offices, public institutions or certain companies may block the use of messenger programs such as KakaoTalk for security reasons. In this case, you cannot use KakaoTalk. 

Once your PC is deregistered, all personal data on your computer will be deleted completely.

If you are seeing this error message even though your network connection is stable, the firewall settings on your PC at work or public places may be the reason. 

Network administrators at banks, government offices, public institutions or certain companies may block the use of messenger programs such as KakaoTalk for security reasons. In this case, you cannot use KakaoTalk. 

You can only register up to 5 PCs per Kakao account. If you want to add another PC, you must deregister one of your current PCs.
