When an account establishes a trust relationship between itself and your account, you become a delegated party. You and all the users you have authorized can switch to the delegating account and manage resources under the delegated permissions.
The user created in Step 3 can switch roles to manage resources for the delegating party.
The system automatically matches the account to an agency. If the matched agency has not been delegated, you have no permissions to access the account. However, you can remove the agency and select an authorized one from the drop-down list box.
