The Credential Store and the ASO Manager both store credentials encrypted using Microsoft DPAPI technology. The Credential Store is the older of the two and has very limited capabilities. The ASO Manager is integrated with your adapters and will dynamically build a UI for editing the credentials which can be displayed using the ShowCredentialsDialog method. The ASO Manager can be instructed to automatically log in to an application when the login controls appear as well. There are many more methods available on the ASO Manager.
