	Assuming that you mean challange questions/answers to verify a user
identity in the case of a forgotten password (as opposed to 2 factor key fob
authentication) by challange-response, ours is optional. When the user 
activates their account via the web they have the option (off by default) to
enter challange/response questions/answers which then may be used to indentify 
them if they can't appear in person with picture ID (which is our normal method 
of resetting passwords). This enables students on coop terms out of town or 
any account user that is travelling and forgets a password an option (not an
easy option, because only the Director is allowed to reset passwords via this
mechanism) other than appearing in person with ID. I don't know what our uptake
rate is (not all that very high I don't expect) but we don't intend it for 
general, use only as a last resort in exceptional circuimstances. 
	Why do you want to make it more general? To reduce staff costs of 
dealing with forgotten passwords? Being able to automate the entire process 
(which I think would be dangerous :-))? Something that I haven't thought of 
(but should have :-))?
