When we shipped passkey support last week, passkeys worked as a second factor — you'd still type your password first, then verify with your fingerprint or security key. That's great for security, but it's an extra step.
Now you can skip the password entirely. If you have a passkey registered on your account, you'll see a "Log in with a passkey" button right on the login page. Tap it, verify with your device, and you're in.
If you've already registered a passkey in Settings → Sign in & security, it just works — no need to set up anything new.
