Is there a way to access all SalesForce data without being an admin? Or, in particular, the ActivityHistories table data? When I query that table as a non-admin level user, I get the following message:

Implementation restriction: activity aggregate relationships only allow security evaluation from non-admin users when a single parent record is evaluated

Requiring admin-level access to use the API requires storing the admin password, which will give any developer admin access to SalesForce and sensitive company information.
