Privilege levels and password security
Hewlett Packard Enterprise strongly recommends that you configure a Manager password to help prevent unauthorized access to your network. A Manager password grants full read/write access to the switch. An Operator password grants access to status and counter, Event Log, and the Operator level in the CLI. After you configure passwords on the switch and log off of the interface, access to the menu interface (and the CLI and web browser interface) requires entries of either the Manager or Operator password.
If the switch does not have Manager or an Operator password, anyone having access to the console interface can operate the console with full manager privileges.
If you configure only an Operator password, entering the Operator password enables full manager privileges.
If the switch only has a Manager password someone without a password can still gain read-only access.
For more information on passwords, see the Access Security Guide for your switch.
