Knowledge-based authentication (KBA for short) is
a form of authentication
where a user is prompted to answer a series of
security questions, where answers
to the questions ought to be available or memorable to the user,
but difficult to guess for others.
Hitachi ID Password Manager includes a mechanism to enroll security
questions from users. It can implement KBA to
authenticate users who may have forgotten
or locked out their password.
