Scanning Fortigate Firewall

Hi Guys,

I have a fortigate Firewall, let’s assume this is the IP for the FW
https://10.68.1.1:10443
I added HTTP web application but still not able scan using credentials and I can’t HTTPS option in the authentication page
How can I scan my FW with credentials and what are the recommended policies for network equipment?

Thank you

Typically speaking I think people have the most success with SSH credentials when it comes to network equipment.
