In order to protect assets of all KuCoin users, we will be upgrading the API Keys process. The default API Keys will initially be set as “Disabled”; users will have to complete the verification manually.
We strongly advise you to login to KuCoin and make sure you generated the API Keys yourself, if that’s not the case, please delete them immediately in order to keep your assets safe.
Thank you for your support, we will ensure to continuously improve security measures for all users.
