A delegated administrator is a user who has been granted limited administrative privileges by an administrator through delegated administration groups. Delegated administrators can perform some administrative tasks without having full access to Setup.
Some functions that delegated administrators can perform are:
A) Set up users and password management.
Delegated administrators can set up and manage users who belong to specified roles or territories, including creating, editing, freezing, and unlocking users; resetting passwords; assigning permission sets; and managing public groups.

Delegated administrators can make updates to permission set configurations if they have been granted access to manage users by an administrator.
