How do you separate the Urchin profiles so each client only sees their report?

Well, with Urchin you can create unique users and just assign that user to the report you that user to see so each time that user logs in, he would only see his reports.

After you log into Urchin as the Admin, go to 'Configuration' / 'Users and Groups' / 'Users' then do an 'Add'.. go through the motion.

After that, go to 'Configuration' / 'Urchin Profile' and do an 'Edit' to the profile you want that user to go to. Under the 'Users and Groups', move the user you want access to that report to the 'Granted Access' column and save.

Now you are done, that user and the admin can only see that report.

Thanks !
