Recently, we have observed an increased number of unauthorized login attempts on Chatwork.
*The set of email and password used for these unauthorized login attempts were not leaked from Chatwork, but it is likely that a third party attempted to login to Chatwork using the email addresses and passwords obtained illegally from the outside.
We are taking measures to block the suspicious unauthorized access as soon as we detect them, but it is sometimes difficult to distinguish them from normal logins, so we would like to ask our customers to protect your account by taking the following steps.
