1. A method for authenticating, through use of a dispersed storage managing unit, a user device request to access a dispersed storage network (DSN), the method comprising: receiving, from a first proxy system element of the DSN, a first authentication request regarding executing a first portion of the user device request; verifying the first authentication request by: verifying that the first proxy system element is an authenticated proxy; and when the first proxy system element is an authenticated proxy, verifying the user device is an authenticated user device; when the first authentication request is validated, sending, to the first proxy system element, a first favorable response such that the first proxy system element is allowed to execute the first portion of the user device request when a permissions list authorizes the user device request; receiving, from a second proxy system element, a second authentication request regarding executing a second portion of the user device request; verifying the second authentication request by: verifying that the second proxy system element is an authenticated proxy; and when the second proxy system element is an authenticated proxy, verifying the user device is an authenticated user device; and when the second authentication request is validated, sending, to the second proxy system element, a second favorable response such that the second proxy system element is allowed to execute the second portion of the user device request when the permissions list authorizes the user device request.
