Good Morning,
I'm building a new SharePoint Server 2019 farm and I am being asked to justify everything I am doing with Microsoft documentation. I don't find anywhere that I need an sp-install or sp-setup account for any valid reason other than if I need to implement power pivot down the road. Would it be totally against best practices if I use my elevated account to install and configure SharePoint rather than a separate, install/setup service account?
Here https://docs.microsoft.com/en-us/sharepoint/security-for-sharepoint-server/plan-for-administrative-and-service-accounts it talks about planning for accounts, but it says the Farm Admin account is the one used for setup:
Farm administrator user account The farm administrator user account is a uniquely identifiable account assigned to a SharePoint admin. It is used to run the following:
Setup
SharePoint Products Configuration Wizard
Domain user account.
Member of the Administrators group on each SharePoint server in the farm.
Member of the following SQL Server role (optional): sysadmin fixed server role.
If you run Windows PowerShell cmdlets that affect a database, this account must be a member of the db_owner fixed database role for the database or a member of the sysadmin fixed server role on SQL.
Thank you!
DM
