I have read other posts here in the forum and managed to get passkey support. The problem is that I use a hardware security key and I have no option to select it like usual. Outside of Vanadium, I do not get any prompt at all for passkeys, only on sites/apps that have a passkey saved. This is a fresh install of GrapheneOS, so I would guess everything is up to date.

Am I doing something wrong?

    I'm curious if this requires google play services to be installed? It would be awesome to see an implementation of support for hardware keys that did not require google play services

      chock-a-block I'm curious if this requires google play services to be installed?

      I did make a note on this in my draft, posted above.

      i did what you wrote in your draft. it works. its a bit unfortunate that fido support isnt in AOSP, but i hope we get there soon. thanks!
