Interesting! I wonder if they’re actually storing the keys in the cloud or if they’re just using Bitwarden as a way to sync keys between hardware.

In any case, it seems like your original suggestion is a good one. Thanks for the info!

I think both passkeys and security keys rely on the hardware being one of your multiple factors. This is what keeps a remote hacker who stole some website’s password database from using the stolen passwords to log in–they don’t have your physical hardware.

You can’t store the passkey in your password manager because your password manager isn’t hardware.

You could store the passkeys in your laptop’s (or phone’s, etc.) hardware, and in fact that’s how passkeys are intended to work.
