You connect to the FortiGate-VM GUI via a web browser by entering the IP address assigned to the port 1 interface (see Configuring port 1) in the browser location field. You must enable HTTP and/or HTTPS access and administrative access on the interface to ensure that you can connect to the GUI. If you only enabled HTTPS access, enter "https://" before the IP address.
When you use HTTP rather than HTTPS to access the GUI, certain web browsers may display a warning that the connection is not private.
On the FortiGate-VM GUI login screen, enter the default username "admin" and then select Login. FortiOS does not assign a default password to the admin user.
Fortinet recommends that you configure a password for the admin user as soon as you log in to the FortiGate-VM GUI for the first time.
