Are there any specific requirements for Passkeys on PC?
I mean iirc you only need a chrome-based browser and Bluetooth on the PC side, and obviously a passkey-compatible phone, right?
because interestingly on one of my 2 PCs it does work.
The one where it does work has a BT adapter from UGREEN which iirc does not support BT5, and the one where it doesnt work is listed as Integrated System Solution Corp. KY-BT100 Bluetooth Adapter, which I heavily doubt supports BT5 either.
The Browser and OS are likely not the issue as I run Brave and Kubuntu 22.04 on both of them currently.
