6.10 Changing an Operating System Password
This topic describes how to change the
admin
and
root
users password to ensure the system
security.
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.
Step 1
Log in to the Linux operating system as the
admin
user.
The default IP address is
192.168.0.120

The default password of the
admin
user is

To change the password of the
root
user, you must run
su - root
to switch to the
root
user. The
default password of the
root
user is
