Heya - @SonicFusion would be correct. Section eight in our Privacy Policy states: [quote]"We implement technical and organizational measures designed to ensure a level of security appropriate to the risk. We use a variety of security technologies and procedures to help protect your information from unauthorized access, use, or disclosure. For example, we store the information you provide on computer servers with access restrictions that are located in controlled facilities. Such information may be retained even after an information deletion request. If you choose to create an account through certain parts of the Bungie Services, you will be required to select a password. This password can be changed once you have logged into the service. It is your responsibility to keep your password confidential. Do not share this information with anyone. If you are sharing a computer with anyone you should always choose to log out before leaving the Bungie Services to help protect access to your information from subsequent users. Please be aware that despite our security measures, no data transmissions over the Internet can be guaranteed to be completely secure. We cannot, therefore, ensure or warrant the security of any information you transmit to Bungie, and you do so at your own risk. Also, any third-party software you may install that interacts with any Bungie Services (“Illegal Software”), in addition to possibly being in violation of the Limited Software License Agreement for those Bungie Services, may create security vulnerabilities for your computer. Bungie cannot be responsible for the privacy or security of any data collected by the providers of such Illegal Software, which may occur incidentally to your use of that software (e.g. harvesting of email addresses, credit card numbers, and other sensitive personal information)."[/quote] tl:dr Players are held responsible for ensuring their accounts and data remain secure. We cannot disconnect any accounts linked. The first thing I'd advise is updating all your passwords and then reaching out to Twitch to see what options, if any, are available to you regarding the account in question.
