> password doesn’t get sent to the server, hash does.

Kind of irrelevant what gets sent to the server and what happens on the server.

Password is already easily defeatable long before it even leaves your computer, thanks to keyloggers and/or password manager breaches and/or old-school shoulder surfing (assisted in the 2026 era by covert filming and AI).

All of which are not vulnerabilities with hardware-backed keys which you don't even need a Yubikey for these days since most modern computers and smartphones have secure enclaves and/or TPMs. (Yubikeys are still great though).

No. The password gets sent to the server. That said, I still enable passwords on servers, but don't ever share passwords between trust domains.
