"Change Site Collection Administrators" page’s direct link - /_admin/SiteAndListExport.aspx

The SharePoint Site collection administrator has full control in the site collection. A site collection administrator can change the appearance of the site collection, get alerts on Quota warnings, add users in the admin group, configure the search site collection settings, access to sites with broken inheritance and much more. Most importantly, this is the person who receives email from system for auto site deletion.

Every site collection must have at least primary site collection admin but we have an opportunity during creation of site collection to add a secondary site collection administrator. Primary or secondary can add even more admins by going to site collection settings.

On this page, we can view, add, remove, and change the primary and secondary site collection administrators for a site collection.

Note

Only a valid single user can be the primary or secondary administrator of the site collection. No security groups are supported in these fields.
