Reseting passwords at a global level

Does anyone know of a way to reset all JDE logins so that the password is the same as their login ID? I'm upgrading from Xe to ERP 8.0 and, during a system freeze, users changed their passwords. On go-live, I need to reset everyone's passwords otherwise the help desk would be getting calls from users who do not remember what passwords they used to use (at the time when we copied the F98OWSEC table over from Xe to ERP 8).

f980wsec is a copy with no table format changes for upgrades from XE to E8. Why not copy the old F98owsec from XE to E8 again as scheduled in the initial task?

thanks.
