Benson needs multiple passwords. Each are found in the bad endings. Using one will lead to a new chain of events on day 8 and the next password will be in the new chain of events.
There is something on Hoss's route on day 7 that helps with day 8 and allows to avoid one of the passwords. Think it happens on Orlando's route too but once you know the right password it will work on every route, day 8 is a universal one.
