Ask HN: Are passkeys just another MFA?

When I initially read about passkeys, I understood they'd replace the email/password flow.

However, I have been using passkeys (when I can) with 1Password and so far my experience is that they "just" replace TOTP that were already pre-filled by 1Password anyway. So in terms of UX there is not a big gain.

I guess that the current advantage is that passkeys are cryptographically secure, while in theory 1Password TOTP auto-fill is based on just matching domain names.

Am I missing something here?
