FATAL: 28000: password authentication failed for user
Most likely this error can occur when your password is wrong or empty.
Make sure your password is valid and its not blank. Makes sure SSIS PackageProtectionLevel property is not set to DoNotSaveSensetive. If you have to set that way then you must provide sensitive information such as Password/Token via some sort of SSIS Variable/Parameters from command line or configuration/environment variable.
