These steps describe how to check the authentication values for the Login Form authentication option in the Credentials settings for the Web App Overview and Web App Scan templates.

These steps assume that you already have a login form ready to test your credentials.


  1. For the web application you want to scan, access the login page.

  2. Type your credentials as necessary.

  3. Upon successful authentication, in the browser console, locate the call that performs the authentication. In this example, the call is login.

    The Form Data section of the Headers tab displays the key/value pairs. In this example, the pairs are uname: Nessus, upass: WAS, and udomain:

  5. In the scan settings, click the Credentials tab.
  6. Click General.
    1. In the Authentication Method drop-down box, select Login Form.
    2. In the Login Page box, type the URL for your login form page.
    3. In the Regex to verify successul auth box, type the regex to match when the credentials are correct.

      Note: In many cases, the regex is text that appears on the login page (e.g., Login Successful!)
