LASS Application Development (Windows CE 5.0)

Windows CE 5.0
Send Feedback

Security services in Microsoft Windows CE 5.0 include the Local Authentication Subsystem (LASS), which enables user authentication independent of the application and the specific authentication mechanism. LASS allows you to support sophisticated authentication mechanisms, such as biometrics, as well as event-based policies to authenticate users. For more information about how LASS differs from the traditional password-based authentication schemes in previous versions of Windows CE, see Local Authentication Subsystem (LASS).

This section includes specific instructions for the application developer. A basic application creates a new AE to guard an action, such as starting the application, and then calls VerifyUser. Depending on your needs, your application can use the default password LAP or a customized LAP. The application can also create its own custom AEs to control the policies for user verification. For more information about creating a LAP, see LASS OS Design Development.
