Does the Canvas Data Portal require a Root level Account Admin user account?

[canvas_support6]

We are active users of the Canvas Data Portal (CDP) and are doing a security review of high level account access in Canvas. We have a Root Level Account Admin service account with a name that suggests a close association with the Data Portal.

We don't know all of the history of this account but I suspect it may have been used in the initial installation. Does the CDP require a high level account to be installed and once installed does that account need to be retained for the CDP to function?

Thanks,

Simon
