I built a website that uses public Ed25519 keys for user authentication (rather than passwords). Users sign the current Unix Epoch time (with the private Ed25519 key) and paste that base64 encoded signature into the login form.

I don't care if the idea succeeds or not, I use it for myself. I like simple, secure things and I feel webauthn is too complex.
