You can disable the Save password check
box on the remote system login window so that users are required to enter
their passwords each time they log on to a remote system.
A system administrator can set up a remote system to prevent users
from saving their password by uncommenting the following line in rsed.envvars:
When a user connects to a system with the option, any saved passwords for
the system are cleared and any further attempt to connect to the system will
not allow the user to save a password.
