Naturally Ubisoft recommends that everyone with a Ubisoft account change their password. Even more, change the password on any other Web site or service where the same or a similar password is used to help ensure the safety of personal information.
a point of concern is if your email, steam, skype or any other service uses the same password and email address to access them, please change them now.
