Step 1 - Select Server Logins in the navigation pane
Step 2 - Click the "New Login" toolbar button
Step 3 - Enter login details
Enter the login name, authentication information, server role membership (if necessary), and select the databases you want the new login to be able to access. Then click OK.
If the login is using SQL Server authentication then you will be asked to confirm the password before saving.
SQL Express requires a strong password (ie a password that is not "trivial"). A mix of alphabetic and numeric characters will usually be ok. If the password does not conform to the new requirements then an error message will appear and you will have to choose a different password.
