This is new, what does it mean?

I am running the latest version of Jellyfin on bare metal Ubuntu server. I have all the latest updates. I have it set up to give access through the net and this is the first time I see this message (attached image) but it says "User successfully authenticated" just curious what this means? 

Thanks in advance.
