How to Reset the User Password in Nessusby Joshua Laud
If you are using Nessus security software and one of your user's has forgotten their password, then you will need to reset their password. Nessus is primarily developed for Unix and Linux network systems. As with most Linux and Unix applications, the easiest way to operate the software is to use the command-line. If you want to reset a user's password for Nessus, you only need to issue one command.
Open your Unix or Linux Terminal. Each distribution has a slightly different method, so consult documentation if you are unsure.
Type, replacing "USER" with the user name you want to reset, "nessus-chpassword USER" (without quotes) and press "Enter."
Type in a new password, press "Enter." Confirm the password and press "Enter" again.
