Permissions allow account owners to provide additional users the ability to manage various aspects of their account and specified devices. These additional users are called Account Members.
From Permissions, click the Invite User button. Enter in the email address for the invitee and select a Role for the account under the drop down (custom roles can be created under the Roles tab). Under Add Device Permissions, the list of devices can be selected individually to provide access for management. Locations, groups or the Entire Account can also be selected for easier assignment.
From the Account Management menu, click on Switch Accounts, and then select the Shared Account you wish to sign in to. The Account Management menu can be accessed by clicking the arrow in the upper right corner of the portal.
