Final answer:
To set the sa password in SQL Server after installation, open SQL Server Management Studio (SSMS), create a new login named 'sa' with a strong password, assign server roles to the 'sa' login, and save the changes.
Step-by-step explanation:
To set the sa password in SQL Server after installation, you can use the SQL Server Management Studio (SSMS) program. Follow these steps:
- Open SSMS and connect to your SQL Server instance.
- In the Object Explorer, expand the 'Security' folder and right-click on the 'Logins' folder. Select 'New Login'.
- In the 'Login - New' window, enter 'sa' as the login name. Choose a strong and secure password for the sa account under 'Password'.
- Under 'Server Roles', select the server roles you want to assign to the 'sa' login. You can grant it 'sysadmin' role to have full administrative privileges.
- Click on 'OK' to save the changes. The sa account will now have the new password and assigned server roles.
Remember to choose a strong password that meets the SQL Server password policy requirements.
