Note that WeBWorK passwords are not shared between courses. So if you have used WeBWorK before, you will still use the initial password as indicated above when logging into a new course. If you want your passwords for all WeBWorK courses to be the same, you will have to change them individually to the same password.

Also note that WeBWorK's system is case sensitive, so you should use only lowercase letters for your username and initial password.
