To change your password in either Linux or Windows, use the TCC website at http://infohost.nmt.edu/tcc
and click on the "Change your password" link (right hand side of the page in the pink box). This will take you to the "TCC Account Management" page. Log in with your username and password and click on the "Account" link. Use the section at the top of the page to change your password. That will change your password for Linux, CMSs (Course Management Systems - like Blackboard and Moodle), and MS Windows.
