About Collections
Collections group together related logins, notes, cards, and identities for secure sharing within an organization. Collections can be created and managed by any organization type. Collections are organization-equivalents to folders, with a few key differences:
Organizations can define access to collections, allowing users or groups to access only the items they need.
Items stored in an organization's collections(s) do not belong to any individual user, but rather to the organization.
Organization-owned items must be included in at least one collection.
Members of an organization will find shared items in their Vaults view alongside personal items, as well as several methods for filtering the item list to only organization items or items in particular collections, for example in the web app:
