My experience with password managers is that they work great for me, because I understand every sharp edge and can work around them. My experience when advising family to use them is that they invariably fail them and they get frustrated. Password managers rely on pretty gross heuristics to work. They are effectively trying to automate something built for a human (choosing, remembering, and entering a password). WebAuthn gives us a real API built by and for machines. This will make the flow much less error-prone and more secure.
