SQL server authentication

I am trying to understand how this works.

I have access to a SQL server DB. When I set up the connection via DBVisualizer (driver SQL Server (jTDS) and leave userid & password blank I connect as expected. I understand this to mean I am using Windows Authentication. This makes sense and is working as expected.

However, when I enter my MS id and password my connection fails. How come I can't connect by passing my username and password?

Long Message:

Login failed for user 'xxxxxx'.

Details:

   Type: java.sql.SQLException

   Error Code: 18456

   SQL State: 28000

My device is windows 10 and I am using DBVisualizer 10.0.15

Hello,

as Roger pointed out, it needs to be set on the SQL Server not in DBVis. Setting can be found in Server properties > Security > Server authentication. You can choose Windows Authentication mode or SQL Server and Windows Authentication mode (which is mixed mode).

See here for screenshot (first image in answer): https://stackoverflow.com/questions/4945815/sql-server-2005-mixed-mode-authentication

Where can the authentication mode be set to mixed?  On the setup I see either the connection tab or the properties tab.  On the connection tab I see name, notes, db type, db driver, server, port, db name, instance, userId, pwd, auto commit, permission mode, and authentication domain.  On the properties tab I see db profile, driver properties, server authentication (which doesn't include a mode mixed or otherwise), qualifiers, physical connection, transaction, encoding, sql statements, connection hooks, color and border, sql commander, query builder, explain plan.  I have a setup that I have tried SQL Server and auto detect SQL Server, server name fully qualified and not, port, db, with an instance and not.  If I login it works because I have a domain account and windows authentication works.  If system account logs in it doesn't work because the system account doesn't have a domain account and I don't see a way to specify mixed mode.  I have googled dbvis and mixed mode and dbvis and authentication mode, etc. etc. etc.  You know what?  I downloaded MS SQL Server DB MGT Studio, logged in, connected the first time everything worked perfectly.  I would like to keep using dbVis because that is where I have everything else setup, but come on man!  SQL Server Authentication, where is it?
