I have not, but maybe I don't follow. I have only seen QR used for onboarding passkeys, never authenticating with them. Untrusted devices and BLE connections seems equally strange as far as threat modeling goes, to me. Have not found it in the Bitwarden docs either. Enlighten me?

Love @bitwarden.bsky.social
I'm already a user and a fan! I use it for the few things that have passkeys in my life currently, but I still don't agree with the overarching implementation of passkeys.

I'm a user and general fan of Bitwarden -- self-hosted. It works great for me, but it still means that to use it on a "guest" device, I need to access my password manager *on that device*. The alternative being accessing my password manager on my trusted device (my phone), and transposing the data.

So by proxy, RC4 with Kerberos is bad.
