About user setup for personalizing portals
To personalize a portal, you must have Is Administrator permissions in the Portal Manager for that portal.
For the latest back office version, as you set up the test user accounts in the back office, you can assign the Portal Admin group, which automatically gives the account Is Administrator permissions in the Portal Manager. This way, you can use the same account to make and review portal modifications.
For any back office version, after you set up the test user accounts in the back office, you can give them Is Administrator permissions in the Portal Manager. See Adding portal administrator users.
