I'd like us to add security query/respond pairs.
Those can very easily weaken security, as the answers are often public
and easy for an attacker to look up, especially when there are only a
few predefined questions to choose from.
I was not advocating predefined questions. :)
If I can enter my own question, then I can come up with some things
that only I and my family know. That requires careful and security-
conscious consideration. Many people would come up with insecure
questions.
Well, I always use randomly generated words for mine.
But I agree, some people would make poor choices there.
There's a limited supply of such personal secrets that I can be sure
I'll remember, so I can't do that for too many sites. It also requires
a not too public life. People who publish their entire lives on
Facebook will have trouble coming up with a question that an attacker
can't find the answer to.
Another reason to randomly generate.

But if randomly generating is best practice, why not automate it for the
user in the form of recovery codes? Take away the temptation to do
something insecure.
