Cover Reports, Diffblue's offering to provide a variety of ways to visualise an application based on information derived from Diffblue Cover, now allows restricting reports uploading to users/clients with a configured username and password. By default, Diffblue Cover will allow any user to upload files to Cover Reports. However, you may want to limit access so that only certain users can upload files.

For example, you may choose to enable authentication if you only want your CI processes to upload data for a project, so that data is comparable and uploaded with a consistent timespan.

See the Authenticating Cover Reports Uploads documentation for more details.
