Also, it makes sure that these commands ensure that all data remains secure and consistent. When access to certain databases is requested I believe that the mixed authentication is the best method to use. The mixed mode will enable both Windows Authentication and SQL Server Authentication by creating a more robust security layer. For instance, a Username and password is required for selection which will need to be uniquely identifiable to that specific user and it also contains multiple characters in it. It will ensure that the operating system token along with the username and password is required every time access is requested into a database.
