There are three methods to change your password.
1. The login page has a "Forgot Password?" Button. See What if I forgot my password?
2. The Dashboard has a “Change Password” link if you hover over your name in the area above the detail panel on the right side of the screen.
3. Your account administrator has a special function to reset your password if all else fails.
Please note that if you attempt to log in five times, your account will be locked. See What should I do if I get locked-out of my account?
