Responses must be an exact match, and our users seem to have a lot of trouble with that, especially after 6 months or so.
We have that problem too. In a new system we proposed, the answers would be case insensitive and would have white space removed.
Some "favorites" change over time so challenges that ask about a favorite are hard to answer after 6 months.
Agreed. Especially when you're 19. :) However, this is a fallback mechanism to be used only when a password is forgotten and there may be fallback mechanisms to the challenge questions if their answers can't be remembered. Like a visit to the helpdesk with a picture ID when the person is on-campus.
We've just recently given our ServiceDesk staff the ability to access a user's challenge responses so they can do confirmations over the phone and accept approximate matches to the answers.
Isn't that kind of like giving them access to the account passwords? -- Gary Flynn Security Engineer James Madison University www.jmu.edu/computing/security
