Types of SQL Server authentications

There are two type of SQL Server authentications

1. Windows Authentication

In window authentication SQL server not required the user name and password to open the server or database. Most of the time windows authentication accessed by the DBA (Database Administrator) to create the database and to give the access to the third user or developer.
