Manages password operations over unsecured connections. You can allow or deny password operations over unsecured connections, and list the current setting.

As a best security practice, you should not disable strong encryption in a production environment. Strong encryption ensures that passwords are transmitted only across secure channels. For test environments only, you can disable strong encryption.
