> It sounds like you want to trivialize a problem that has existed for way longer than computer science and systematically relies at some point on human memory if you want a certain level of security and secrecy.

Assuming the "problem" you are referring to is authentication, this is not necessarily true. "Something you know" is just one auth factor of several. Using a thumbprint (something you are) to grant access to a private key stored on a device to sign a challenge does not rely on human memory, and is probably more secure than using a password in most cases.

An argument can also be made that using a password manager implies that you are specifically doing the opposite of relying on human memory for authentication.

That said, I also disagree with the premise of the original comment that "Passwords should be dead soon and this article should be irrelevant soon after." They will be around for a while, although I hope passwordless mfa can soon replace them as the default choice.
