I try to log in, but I get a message that I need to wait 72 hours without using it and try again.

Someone with a malicious intent may try to compromise your Kakao Account by stealing your Kakao ID and password. Kakao has protection measures to prevent such account compromise.

If you get a message after changing a phone number, "The account is currently active under another phone number. Please do not use Kakao Talk on your previous device for 72 hours and try logging in again," and can't log in, please wait 72 hours and try logging in again.

If you keep experiencing login failure, check the status of your previous phone number (active, deactivated, etc) and contact our Customer Service.
