This article introduces four ways for SQL Server users to enable Mixed Mode Authentication from installation to use.
Once you set SA account during SQL Server installation, Mixed Mode Authentication would be available after finishing installing SQL Server. When you connect to SQL Server database, there would be two authentication modes for you to choose.
Even though you don’t choose Mixed Mode Authentication in SQL Server setup progress, following two ways still could help to enable SQL Server Mixed Mode Authentication.
2. Click on Properties.
3. Click on Security on the left pane.
4. Check SQL Server and Windows Authentication mode under Server authentication section. Click OK.
N'Software\Microsoft\MSSQLServer\MSSQLServer', N'LoginMode', REG_DWORD, 2
[Note: 2 indicates mixed mode authentication. 1 is for windows only authentication]
Step 1: Open the registry editor.
Step 2: Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.10.SQLEXPRESS\MSSQLServer
Step 3: Change the value of LoginMode from 1 to 2.
Step 4: Close the registry editor.
Tips: One thing to note is I had a few different options under the Microsoft SQL Server branch so you may need to take an educated guess if yours is different.
