I'd disagree with that -- it makes the account only as secure as the
secondary questions, which is usually less secure than the primary
password (if it was as secure, why wouldn't you just use it as the
primay means of authentication if it was less likely to be forgotten?).
To my mind, unencrypted email is better than secondary questions but
neither is particularly good.  Better would be encrypted email, best
would be client side SSL certificates.  Unfortunately not many people
use encrypted email and few keep SSL certificates around, especially not
ones that are certified by a trusted CA.

As an intermediate measure, I quite like the way NatWest goes about
things (from a setting up point of view) -- they require you to phone
them and convince them that you are who you say you are before sending
you your activation code, which comes in the post a few days later.  You
use this code to activate your account and set up your PIN and password.
Should you forget either, you have to phone them again.  This is
probably a bit too much hassle for your average shopping site though...

I believe that the CC companies have a new scheme coming out soon, which
should make all this a lot easier -- after attempting to purchase
something online, you have to go to the CC company's site and satisfy
them that you really are you, before they authorise the transaction.
This means that you've only got one set of super-secure credentials to
remember, and that they can be secure in defining and maintaining those
credentials.
