Techniques are described herein for allowing automated assistants serving users to access data controlled by others, including resources available to automated assistants serving others. In various implementations, a voice input may be received from a first user. A task request may be recognized from the voice input and analyzed. In response to the analysis, a determination may be made that the task request relates to a second user. An access control list relating to an automated assistant engaged by the second user may be checked to determine whether the first user has appropriate access rights as regards the second user. In response to determining that the first user has appropriate access rights as regards the second user, action may be taken on the task request.
