Doesn't work that way. Passwords are inferior but still a strong layer of defense. You are putting all your eggs in one basket again. The lesson from passwords is that a single factor of authentication is inherently inferior to multiple factors of authentication. From a threat actor's perspective, even a yubikey is a matter of one well planned attack (physical, compromised host,etc) and by nature newer factors of auth don't get treated with hostility like with passwords. They are better than passwords but what I see is people moving away from MFA to only a yubikey for example. Like you are now one lost yubikey away from your whole company getting owned lol.
