You can change your password at any time while logged into the CLC. First, hover over the circular gear icon at the top right of the CLC home page. Next, click on 'My Account' on the menu that appears. Then, click on the 'Options' button at the top right of the Preferences box. Click on 'Change Password' where you will then need to insert your current password and the new password you would like to use.

This will only change your CLC password, not your network password.
