This only changes your password for submitting assignments for this class. It does not affect your system password or any other class submission system.
You should not make this password to be the same as your login password. The instructor and the TA have access to this information, including your course password, so it is not secure.
If you do not receive an email confirmation of your password change, or if you receive a password change message when in fact you did not do anything, please contact me (tson AT cs.nmsu.edu) as soon as possible.
