We need a possibility to create confidential records in Secure Store with limited lifetime.
Such records must be deleted automatically by WF when expired - it is natural for a such sensitive data to be valid within limited amount of time.
For instance, during a session we grab info from different web sites.
User credentials for these sites we would like to temporarily keep in Secure Store.
When the session expires (like 30-60 minutes) we would like WF to delete such records
