Set an Encryption Password

If you set an encryption password, Nessus encrypts all policies, scans results, and scan configurations. You must enter the password when Tenable Nessus restarts.

Caution: If you lose your encryption password, it cannot be recovered by an administrator or Tenable Support.

To set an encryption password in the Tenable Nessus user interface:

  1. In Nessus, in the top navigation bar, click Settings.

    The About page appears.

  2. Click the Encryption Password tab.

  3. In the New Password box, type your encryption password.
  4. Click the Save button.

    Tenable Nessus saves the encryption password.

To set an encryption password in the command-line interface:

  1. Access Tenable Nessus from the CLI.
