Which type of accounts can be updated by designated users?

Designated users typically have the ability to update User Assign Accounts. This type of account is specifically set up to allow certain users within an organization to manage and modify the data associated with that account. User Assign Accounts are tailored for individual users and often have a level of security and permissions that restrict access to only those designated users. This makes it easy for organizations to delegate responsibility for data management while maintaining control over who can make updates.

The other account types have different characteristics that limit user capabilities. Global Accounts are generally set up for organization-wide access, making them less suited for individual updates. Private Accounts are restricted to a single user with no sharing capabilities, which means designated user updates wouldn't apply. Shared Accounts, while accessible by multiple users, may not specifically allow for updates by just any designated user unless they have the necessary permissions. Thus, User Assign Accounts stand out as the correct choice for this scenario.
