@Vlad-Nirky I asked about this in the ubports Matrix channel some time ago, because of course I want to implement the Yubikey challenge-response thing for KeePassRX (it's supported by the underlying Rust library). I was told the OS doesn't have full integration yet, at the OS level. But as a disclaimer, I didn't actually bother trying it myself yet lol. The Yubikey WILL be picked up as a USB device, at least, if plugged in. It shows up as an HID keyboard to make use of the pre-programmed typed password feature thingy of Yubikeys. I don't know if any of the other features of Yubikeys would work yet, though. One way to find out...

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

@Keneda This was to inform about this porting. Thanks for the move.

@lduboeuf Thanks for the answer Lionel. Well, i have made some tries but without success. Finally, i have remove the pip3 install of 8.3.1 and reinstall with snap and now it's working. There was something wrong with the blob fdc55cec6c2e

Thank you all! Here are a few path to explore. And some interesting topics to explore.

@Vlad-Nirky good news !
