Technical Tip: SMS Two Factor Authentication for guest users

To send SMS notifications to guest users, add a mail server in the sms-server configuration of the FortiGate using the following commands:

config system sms-server

    edit sms-server

        set mail-server 1.1.1.1

    next

end

Then it is needed to enable the following under the guests group:

config user group
    edit 'guests'
        set group-type guest
        set mobile-phone enable
        set sms-server custom
        set sms-custom-server 'sms-server'
    next
end

Note:  FortiGuard offers SMS service, however a license is required. To check if the license is already activated, refer to this article: Technical Tip: How to check if there is a FortiGuard SMS license active.
