Your administrator will provide you with a username and password to log in to the site (if SSO is not enabled), as well as the URL (web address). When you go to the front page of the site (the login page), you may see a link to request an account. This form is only for participants. Do not use this form to request an account, as participant accounts have an entirely different set of privileges, which are not appropriate for a researcher.
If you have forgotten your password and the system is configured to allow password retrieval, you will see a link where you may choose to have your password reset and a new password emailed to you. Once you log in, you will be presented with a Main Menu with a few options.
