Can more than one attendee use the unique URL to attend the seminar through registration?

I'm hosting a seminar through registration, and I heard a unique URL is generated to join for each registrant, but I was wondering if an attendee can share that unique URL with others, if they can, is there any way to prevent this?

Your request can be available for "Allow panelists and attendees to join from multiple devices".

Web portal > Webinars > Click the webinar name (Not "Edit") > Invitasions > Registration Settings > Other options > uncheck "Allow panelists and attendees to join from multiple devices"
