Aliases in Enterprises are defined and managed at the enterprise level only. They are distribution lists for the Release management workflow. Only Administrators can create Aliases and assign other users or Teams to an alias. Specifically, an Administrator needs the Manage users and teams global permission in order to create aliases and assign other users or teams to an Alias.

Aliases are found under Enterprise settings on the User account menu. At the creation of an Enterprise, all members of the enterprise are automatically added to the All enterprise users team, and users of that team, as well as the entire team, can be added to an alias.
