As described [here](https://community.denodo.com/docs/html/browse/7.0/platform/installation/postinstallation_tasks/postinstallation_tasks_in_virtual_dataport/change_the_default_password#), you should actually delete the admin user after you’ve created another administrator, or at least change the password of the user In VDP. Only administrative users are able to log into the ITPilot administrator tool, and only using the correct password for that user set in vdp. You can check what users are administrators by going to Administration > User Management and checking the value under “Type”, and administrators should be listed first.
If you are able to access the Administrator tools, you are in fact logged in with one of those administrative accounts.
Hope this helps!
