# Include Witness Server (Configure Database Mirroring Security Wizard)
 [!INCLUDE [SQL Server](../../includes/applies-to-version/sqlserver.md)]
  Use this page to specify whether you want to include a witness server in this security configuration for database mirroring.  
  
 **To configure database mirroring by using SQL Server Management Studio**  
  
-   [Establish a Database Mirroring Session Using Windows Authentication (SQL Server Management Studio)](../../database-engine/database-mirroring/establish-database-mirroring-session-windows-authentication.md)  
  
-   [Start the Configuring Database Mirroring Security Wizard (SQL Server Management Studio)](../../database-engine/database-mirroring/start-the-configuring-database-mirroring-security-wizard.md)  
  
## Options  
 **Yes**  
 Click to include a witness server instance in the security configuration. The witness is necessary for high-safety mode with automatic failover, which supports automatic failover to the mirror server instance if the principal server instance fails.  
  
 **No**  
 Click to configure security without a witness.
