Re: [webauthn] Proposal for password-only authentication using ES256 (#2091)

>You could also brute-force a `(credential-ID, signature)` pair

Yes, I also realized that last night, along with the fact that an attacker could choose the salt for a victim, and have precomputed dictionaries for that salt. And most damning of all, that actually makes phishing attacks attractive for an attacker. That realization dampened my enthusiasm for the whole thing a fair bit.

>But perhaps some [PAKE](https://datatracker.ietf.org/doc/draft-irtf-cfrg-opaque/)-based approach

My intention was to cram something almost as good as a PAKE into the existing framework that WebAuthn provides, but given the above, it is clear to me that it isn't almost as good as a PAKE, so yes, I agree.

Thanks for humoring me!
