Manage site admins
This article describes how global admins and SharePoint admins in Microsoft 365 can add and remove site admins (previously called "site collection admins"). If you're an owner of a communication site, or a site that belongs to a Microsoft 365 group, see Manage your SharePoint site settings for info about giving people access to your site. If you're an admin for a classic site, see Manage your SharePoint site settings.
If you're a global admin and want info about assigning other users the SharePoint admin role in Microsoft 365, see Assigning admin permissions.

Select Permissions. For a group-connected team site, you can add and remove group owners and additional site admins. For other sites, you can add and remove site admins and change the primary admin. Note that if you remove a person as a primary admin, they will still be listed as an additional admin. For info about each role, see About site permissions.
