I can't say I agree with his conclusion at all.
He isn't wrong about many of the problems with passwords (and more importantly password reset mechanisms), nor is wrong about the extreme privacy that must be forfeit to move beyond it. I'm not willing to give up that privacy.
He lays out a lot of the solutions to common issues with passwords in that article. Don't reuse passwords, keep multiple email accounts for particular purposes, and don't enter actual information into security questions. A lot of the issues with the above can be solved using a proper password manager.
The bigger issues he brings up, I think, relate to over the phone verification using credit card or social security numbers. It is pretty clear those mechanisms are nowhere near as secure as they should be, especially considering these are often used for utilities, banking, etc.. Not only are these accounts that hold a lot of important information about you (or your actual money), they are accounts you can't just abandon and remake. You need to be able to maintain access to these accounts regardless, yet they are also the most critical ones to maintain sole control over. I'm still not a fan of giving up additional privacy for these accounts - perhaps some sort of in-person verification could be set up for such instances.
