Hi RichardSa,
You need to select SQL Server Authentication.
Connecting Through Windows Authentication
When a user connects through a Windows user account, SQL Server validates the account name and password using the Windows principal token in the operating system. This means that the user identity is confirmed by Windows. SQL Server does not ask for the password, and does not perform the identity validation. Windows Authentication is the default authentication mode, and is much more secure than SQL Server Authentication. Windows Authentication uses Kerberos security protocol, provides password policy enforcement with regard to complexity validation for strong passwords, provides support for account lockout, and supports password expiration. A connection made using Windows Authentication is sometimes called a trusted connection, because SQL Server trusts the credentials provided by Windows.
Connecting Through SQL Server Authentication
When using SQL Server Authentication, logins are created in SQL Server that are not based on Windows user accounts. Both the user name and the password are created by using SQL Server and stored in SQL Server. Users connecting using SQL Server Authentication must provide their credentials (login and password) every time that they connect.
