I agree completely.

The article above is pretty dated (which is noted in the post), and so leaves out some better options for security that are available today, such as authenticator apps for 2fa. In the context of when it was published, it was an excellent and important stepping stone in security awareness, but working with the tools of the time.

Now, we have better options and Troy Hunt (among others) has covered many of them in separate posts over the years.
