6.10 Changing an Operating System Password

This topic describes how to change the admin and root users password to ensure the system

You are forced to change the password when logging in to the system as the admin or root
user for the first time.
If the admin or root user enters incorrect password for three consecutive times within 5
minutes, the account will be locked.
Do not attempt to log in to the client when the user account is locked, because the system will
recalculate the lock duration.
