Hi What I think has happened is that your username and password was used to log in to your account. The most common method for attackers to obtain user/password in these situations is malware installed on your computer. You should consider anything in your account compromised At a minimum you should change your password to something you don't use on any other accounts. You may want to delete and recreate your account fresh for peace of mind. Consider enabling 2FA which would prevent someone with only the username and password from logging in to the account.
