Administration privileges (Delegation)
Introduction
Nextcloud has built-in functionality which permits administrators to delegate authority to others without granting them full administration privileges (and without making them a member of the admin group).
This administration privilege delegation functionality is supported by many shipped and ecosystem apps that have their own settings areas under Administration settings.
Usage
By default only members of the admin group can access Administration settings. You can create additional user groups (or use existing ones) and then grant these groups access to specific settings.
While logged in to an account that is a member of the admin group, go to Administration settings -> Administration privilege. You will be presented with the list of settings pages and sections, including for any installed apps, that support delegation.
By clicking on the combo box, you will be able to choose which groups are able to access the selected settings. You can revoke access at any time by removing the group from the selection (or, if you wish only to revoke access for an individual account, by removing that account from the configured group).
