When you initiate a password reset, you will be provided a link that brings you to a page like this:
It is important to change your password immediately on the page that loads when you press "Log in." It is the only time you will not be required to know your "Current Password" in order to change it. See below for a screenshot of the page that loads without the "Current Password" requirement.
If you haven't recently done so, initiate a password reset here.
