What should be done with a single user in SQL Server?

If you want to create a single user in SQL Server, you can follow the steps below:

1. Open SQL Server Management Studio (SSMS) and connect to your SQL Server instance.
2. Expand the “Security” folder in the File Explorer.
3. Right click on the “Login Name” folder and choose “Create New Login Name”.
4. On the “Username” page, input a login name that can be any name of your choice.
5. Choose “SQL Server Authentication” on the “Select Page”.
6. Provide a password and confirm it.
7. Choose the appropriate server role on the “Server Role” tab, or if you are not sure, please keep the default setting.
8. On the “User Mapping” tab, select the desired database and assign the corresponding role or permissions to that user.
9. Click “confirm” to create the user.

You have now successfully created a single user, assigned the appropriate permissions and roles. The user can now access SQL Server using the provided username and password.
