Check Scan Authentication Status
When a scan requiring authentication is completed, you can verify whether the authentication was successful for the scan.
Double-click the scans row or select the scan and from Quick Actions menu, click View to display the WAS Scan View. The Overview section includes Authentication Status: Successful or Failure.

Review the authentication status and take action as appropriate:
Successful: This means the scanning engine successfully authenticated to the web application during the scan.
Failure: This means the scanning engine failed to authenticate to the web application during the scan.
