/**
 * A modal which allows you to change your current password. It has three textfields: Current Password, New Password, and Confirm Password. It will invalidate if current password is not
 * passed in or if it is the wrong password, or if new password and confirm password do not match. This modal is called from the FwHeader component (if they have a GC generated
 * password, they will be forced to select a "secure" password) and the Profile page. There is no configuration needed for this modal, and you do not need to call it, since it is handled by
 * components within Ember FW GC.
