I watched it and although it was interesting, it needed a software for Java runtime which seems to be specific for SailfishOS and doesn't exists for UT. Newpipe also separates backend and frontend codes so it was easier to do. Not many apps does it the same way, sadly.

Late to the discussion, but on desktop the Yubikey requires some packages installed. So integration would not be straightforward, but I guess something can be hacked if need be. To have the OS support it natively is another story as I doubt an app can bring Yubikey's features to other apps, the browser and wherever it is needed...

Hello. I'm replying to myself: it seems that the ticket is still open and ultimately still being processed. Let's wait and see... https://gitlab.com/ubports/development/ubuntu-touch/-/issues/2238
