If you have forgotten your password, you can easily request a new one. Start by going to the login page then press on "Forgot password?"
You will be asked to enter the email you have registered with, then directed to this page below. You will then recieve an email with your username and a recovery code, which you will enter to confirm that this is who you are!
In the last step you get to choose a new password and then you are back on track!!
