Login with Passkey, "Use for vault encryption"


One more question: How come passkeys that are stored in a Bitwarden browser extension do not seem to be PRF-capable, even when used on a PRF-capable browser? For example, when registering a passkey for one Bitwarden account, the passkey can be stored as a login item in the Bitwarden vault of a second account; however, when doing this, the first account shows the registered passkey with the status “Encryption not supported”.

Perhaps storing a Bitwarden passkey in a Bitwarden vault is not generally a good idea, but I don’t see why vault storage of passkeys should exclude the possibility of storing passkeys that require PRF. There will be use-cases that need such functionality.
