If Passwords Were Unphishable...

Why are passwords such a mess?

The answer to this is deeply sad. It is because we have done a fantastic job on usability of passwords. They’re so usable that anyone will type their password anywhere they see the word “password” with a box next to it. Phishing is utterly trivial because we have trained the world to expect to be phished every time they see a new website.

But if/when we ever get to a stage where passwords aren't phishable, there's an interesting corollary, as this thoughtful post points out:

If your password is unphishable, then it is obviously the case that it can be the same everywhere. Or it wouldn’t be unphishable. The only reason you need a password for each site is because we’re too lame to fix the real problem. Passwords scale just fine. If it wasn’t for those pesky users (that we trained to do the wrong thing), that is.
