When we developed this feature, our purpose was to demonstrate a proof of concept for how the PRF extension enabled zero-knowledge products to use the passkey specification for login and decryption.
Since then, we’ve kept an eye on feature adoption among our cloud users, passkey adoption broadly, and PRF adoption by platforms and authenticators.
I expect that eventually login with passkey will be an option across all of our clients, and in many cases the easiest way for a user to get into their vault. After all, when the stars align, it’s a passwordless, phishing resistant login method that even provides a kind of 2FA!
But for the immediate future, especially with the current state of PRF support, expanding this option to additional clients is probably not feature Bitwarden should focus on to deliver an easier login experience. As we update our public roadmap, you’ll hear more about where specifically our near-term focus is, but that’s the long view.
