Products
Open Products to change that set later. A product that is on shows status New, and its trial settings are disabled. Switch products on or off, then click Save changes. CDN setting opens CDN limits and features for this account. Starting the product is still done by the customer, not on this page.
Sign in as the customer
In Actions, rest on the arrow. It is labeled Log in. That control opens the Customer Portal without asking for the password. The three-dot menu on that row is Edit only.

The dialog changes the email, name, and language, and sets one group: Administrators, Engineers, Purge and Prefetch only (API), Purge and Prefetch only (API+Web), or Users.
Delete an account
On Delete account, the status is Inactive. Click Delete account.
