database - Can I remove sa login from SQL server?

Question

I am a beginner in database field and this question might sound too stupid but I want to know why there is a login called sa and can I delete it?

I want to delete it because it seems to have pretty serious privileges on database server!

If it matters, I am using SQL Server Express 2008.

Answer 1

You can't remove the sa account but you can rename and/or disable it. Arguably this is good practice as otherwise you have a known username that an attacker could launch a brute force password attack against.

Just make sure if you disable the sa account that you have another account with administrator privileges.
