SSIS Connection Manager Not Storing SQL Password

You can store the password in the configuration string by going to properties and adding password=yourpassword, but it’s very important to put a space after the ; on the line before password and after the ; on the password line, as shown below:

Data Source=50.21.65.225;User ID=vc_ssis; 
password=D@mc317Feo; 
Initial Catalog=Sales;
Provider=SQLNCLI10.1;
Persist Security Info=True;Auto Translate=False;
Application Name=SSIS-PKG_CustomerData-{2A666833-6095-4486-C04F-350CBCA5C49E}IDM11.Sales.dev;
