Put another way, a Website Host is merely a stand-alone website. That website will host (or administer) the studies which are built on it. Does that mean the studies are connected? No. Two studies under a single host are just as independent as two studies each under their own host. The advantage of housing studies under a single host account is the ease with which which forms can be copied and shared across studies.
Note: Most users will never need to register for Clinical Studio. Those users include roles such as Data Managers, Coordinators, and Study Monitors. Users who serve under these types of roles are added to a host account by a Website Host Administrator of their respective study.
Once a user is added to a study by a Website Host Administrator, they will receive an email with their user ID, temporary password, and a link to Clinical Studio. Clicking the link will open Clinical Studio and prompt the user to change their temporary password to one of their own choosing. The new user can begin using Clinical Studio for the study to which they were added.
Each Clinical Studio user has a unique username (email) and password. To maintain the secure integrity of Clinical Studio, login credentials should never be shared with other users.
