Should an account be set up and used solely to install SQL Server?

Question

I'd like to follow best practices. However, is it overkill to create a new service account (with minimal access and no special rights) and then use that account to install SQL Server?

Are there downsides if I do the installation under my administrator account?

Side note: I already have separate service accounts that will run SQL Server engine and SQL Server Agent service.

Answer 1

There is no need or benefit to installing under a dedicated account as long as you are following other account-based best practices.
