Access Authorization
The OSD password function is used to control locking and unlocking
consoles. To prevent unauthorized switching, the administrator can use
the password to lock the console on a particular computer, or even a null
port to prevent unauthorized access of any computers.

in the KVM, any time someone wants to alter the value stored in KVM
such as station name, he will be asked to provide the password.
