  Modern trend sees a lot usage of \textit{honeywords} (or fake password) for
protecting the original passwords in the password file. However, the usage of
\textit{honeywords} has strongly been criticized under the different security
and usability parameters. Though many of these issues have been successfully
resolved, research in this domain is still facing difficulties in
\textit{achieving flatness} (or producing the equally probable
\textit{honeywords} with reference to the original password). Though recent
studies have made a significant effort to meet this criterion, we show that
they either fall short or are based on some unrealistic assumptions. To
practically fulfill this flatness criterion, we propose a
questionnaire-oriented authentication system based on the episodic (or long
term) memory of the users. Our study reveals that proposed mechanism is capable
of generating significantly improved flatter list of \textit{honeywords}
compared to the existing protocols. The subsequent discussion shows that the
proposed system also overcomes all the limitations of the existing state of
arts with no lesser than $95\%$ goodness.
