What is the difference between Windows and SQL Server authentication?

In Windows authentication, the user should first authenticate himself within Active Directory. SQL Server authenticates users through the Windows principal token in the OS. With that, SQL Server does not ask for a password for identity validation.

A Login is an identity used to connect to a SQL Server instance. A User allows you to log into a SQL Server database and is mapped to a Login. So you will need to first create a Login, before you can create a User in SQL Server.

What is SQL Windows authentication?

Windows authentication uses a series of encrypted messages to authenticate users in SQL Server. When SQL Server logins are used, SQL Server login names and encrypted passwords are passed across the network, which makes them less secure.

A login is a security principal at the scope of the SQL Server instance, and a SQL Server instance can contain numerous databases. There are two main types of logins; Windows authenticated login and SQL Server authenticated login. Simply stated, a login allows you to connect to a SQL Server instance.
