Hi,
Yes... you can do that using cli mode.....
acs reset-password
To reset the `acsadmin' administrator password to the default setting, use the acs reset-passwordcommand in the EXEC mode.
acs reset-password
Syntax Description
No arguments or keywords.
Defaults
This command resets the ACS administrator `acsadmin' password to the default setting (default). Resetting this password does not affect other ACS administrators.
Command Modes
EXEC
Usage Guidelines
You cannot use this command on a secondary ACS node.
After you use this command, you must access your primary ACS node via the web interface and change the password. If you use the default password for the web interface (default) to access the ACS Configuration mode (which requires you to provide the web interface username and password), the login fails and the system prompts you to change the default password.
Examples
acs/admin# acs reset-password
This command resets the 'ACSAdmin' password to its original value.
Are you sure you want to continue? (yes/no) y
Password was reset successfully
Once done use the default password which would be a factory default...... :-)
Please do rate if the given information helps.
