Video is a bit of a problem for me - is there a written reference of what you did?
I typed "ssh localhost", it displayed a QR code and I used my phone (with skubit BitID client) to scan and authenticate it.
In the second attempt, I copy&pasted the BitID URL into a browser, replaced "bitid://" with "http://", the QR code showed in the browser instead of the terminal and I also scanned & authenticated.
Sorry the video is fuzzy.
