+## User Types
+
+When adding users to your Bitwarden Organization, you can grant certain levels of access by user type. Options include Owner, Admin, Manager and User. See further details below: 
+
+### User 
+- Most common user type
+- Only have access to assigned collections 
+- Consumers of shared items in addition to their individual vault items
+- Only work with items under collections they have been associated with
+- Unable to create collections
+
+### Manager
+- Only administer a collection it is associated with by an Owner or Admin
+- Access and manage assigned collections in an organization
+- Create new collections and modify the assigned collections 
+- Able to set user access for assigned collections
+
+### Admin 
+- Access and manage all items, collections, and users in your organization
+- Invite and confirm users to join an organization
+- Manage Enterprise Policies
+- Manage Groups
+- View Event Logs
+- Export organization vault data
+- Normally only a few select Admins in an organization
+
+### Owner 
+- Highest level of access
+- Manage all aspects of the organization
+- Manage billing, subscription, and integration mechanisms
+- Normally only a few select Owners in an organization
+
+{% note %}
+Once the user or user’s group is saved with their Collections access, the user will inherit those items into their Vault view.
+{% endnote %}
+
+## Access Control
+In addition to defining the User Type, Access Control determines a full or partial view of the collections within an organization.
+
+Choose **all items** or **selected collections** to set the appropriate access.
+
+Choose **read only** for the appropriate collections.
