Password Strength
The default username/password is
cisco
/
cisco
. The first time that you log in with
the default username and password, you are required to enter a new password.
Password complexity is enabled by default. If the password that you choose is not
complex enough (
Password Complexity Settings
are enabled in the Password
Strength page), you are prompted to create another password.
See
on how to create a user account.
Since passwords are used to authenticate users accessing the device, simple
passwords are potential security hazards. Therefore, password complexity
requirements are enforced by default and may be configured as necessary.
To define password complexity rules:
STEP 1
Click
Security
>
Password Strength
.
STEP 2
Enter the following aging parameters for passwords:
•

—Enter the number of days that can elapse before
the user is prompted to change the password.
NOTE
Password aging also applies to zero-length passwords (no

to enable complexity rules for passwords.
If password complexity is enabled, new passwords must conform to the following
default settings:
•
