Devices can be registered using either a one-time passcode during the registration of the device or application, or to allow automatic registration.
When a package is deployed, an Application Connection Template is automatically created for it. As long as the user is able to authenticate to the security configuration associated with the application, they are registered. If automatic registration is disabled then the administrator must generate a passcode. For details, see Sybase Control Center online help and search for Registration and Onboarding.
