Resetting a Nessus User Password in Linux
By default, Nessus is installed in the /opt directory on Linux. To change a Nessus user password, follow these steps:
Navigate to the Nessus sbin Directory
In the terminal, navigate to the sbin folder inside the Nessus directory:
cd ~/../opt/nessus/sbin/

List Nessus Users (If Needed)
To change a user’s password, you’ll needto know their username. If you already know the username, skip to Step 3.
To view a list of Nessus users:
./nessuscli lsuser

Change the Password
Now you can change the password for the account using the username from Step 2. Replace username with the actual Nessus username:
./nessuscli chpasswd username
Enter the New Password
You’ll be prompted to enter the new password. Once done – voila! Your Nessus user password has been successfully changed.
