enter image description here Although the main points are right, but now six words are needed, which is both inconvenient to remember, and inconvenient to type.

My question is, has then been any case studies on the most convenient schemes for entropy produced, where convenience is a tradeoff between memorablity and easiness to type.

  • Random Characters are easy to type but hard to remember

  • This is impossible to answer objectively. Every person will have a different idea of what is convenient enough or secure enough and every situation is different such as a bank compared a college student's senior project will require a different ratio of security to convenience. I would argue it's better to be more secure than convenient then tune it down over time to fit your user's needs. – GingerBeard Apr 12 '15 at 02:29
  • @GingerBeard That's why I am asking for a scheme. Both a banker and college student want the most bits for their inconvenience, whether its because they want more bits or less inconvience. – PyRulez Apr 12 '15 at 02:32

    I assume you mean in English? Different languages and cultures will have different results of any "study". – schroeder Apr 12 '15 at 04:30

    While I can't be certain, I assume the original poster meant a study along the lines of: http://en.wikipedia.org/wiki/Case_study – GingerBeard Apr 12 '15 at 08:06
  • I answered [a similar question](http://security.stackexchange.com/a/85762/8340) yesterday. I'm not aware of any studies as increasing how easy to type is a very subjective measure and also reduces entropy. – SilverlightFox Apr 13 '15 at 09:23
