Storing sensitive information (such as the password) within the connection string can affect the security of your application. Connection strings saved to the application configuration file are not encrypted or obfuscated, so it may be possible for someone to access the file and view its contents.
If you do not choose to use Windows integrated security and your database requires a user name and password, you can omit them from the connection string, but your application will need to provide this information to successfully connect to the database. For example, you can create a dialog box that prompts the user for this information and dynamically builds the connection string at run time. Security can still be an issue if the information is intercepted on the way to the database.
Storing sensitive information (such as a password) within the connection string can affect the security of your application. Using Windows integrated security is a more secure way to control access to a database.For more information, see Protecting connection information.
