Correct. You need only store the realm/user/password digest. The chief
problem with digest authentication is that the web site has no control
over the UI. Among the many issues, this makes it tricky to reliably
capture a digest in the first place without the server at least
briefly knowing the password. I don't know if webauthn corrects this
or makes similar blunders.

Respectfully, if you didn't know that http digest authentication
doesn't require server-side password storage, and more importantly
don't simply admit it now that you've been informed, how trustworthy
can your understanding of web authentication be?

I can't speak to Steven, Paul, the w3c or any other non-posters to
this thread that you wish to employ in an appeal to authority fallacy
but with due respect, I think you hold a myopic view of network
security. For better or worse, security is a zero-sum game. The budget
stays proportional to the value of the asset being protected. When you
spend it on low-impact improvements you don't have it for the many
improvements with a higher impact than whether a web site knows the
password you chose for that web site.
