Microsoft® SQL Server 2012 Unleashed

Managing SQL Server Logins

You can create and administer logins easily using SSMS. You can use T-SQL as well, but the GUI screens are often the best choice. The GUI screens present the configurable properties for a login, including the available options, databases, and securables that can be assigned to a login. The number of configurable options is extensive and can be difficult to manage with T-SQL.
