There are two ways to change your password:
1. If you are not able to log in to your account, go to the log-in page and click forgot password, you will be prompted to enter your new password twice, once you press continue you will be emailed a verification code that you will need to enter in the next window. After you have been verified, your new password will have been accepted and you can log in with your new password.
2. If you are in your account, and want to change your password, click on the down arrow next to your name for the drop down menu, then click on Settings, click change over password. You will then get a form to fill out, change your password and submit.
