Or supply answers which don’t match the questions asked.

What’s your mothers maiden name? %7!%@#

[Maurice Tift]

  Or supply answers which don’t match the questions asked.

  Where was your least favourite job?
  The Death Star

  What was the first car you owned?
  DMC Flying Delorean

   Another method is to use the 'make up your own question' feature if it's offered. Put something like Page 57 where the question really means "What is underlined on page 57 of my favorite book?"

[Dr. Sivana]

What’s your mother's maiden name? %7!%@#

Actually, some guys (and gals) might use such a name to describe their mother-in-law.

[ops33]

Exactly what I was thinking. Choose a different birthday, for instance. Just so long as you can remember.

What’s your mothers maiden name? %7!%@#

Hard to remember.

It's better to come up with a system that will generate replicable results, but will somewhat obscure the answers.

One method might be to run your answers through rot13.

echo Zeugma | rot13

Yeah rot13 isn't a secure encryption mechanism, but it obfuscates your answer enough to defeat some random joe from guessing it.

Alternately, use a hash program to generate a predictable hash.

echo Zeugma | sha1sum
4a8e7fd115c3b65b01f42fa64c58fc3e8abe960e  -

In this case, you can choose the first 8, last 8, or any combination thereof to create a pretty darn good random answer that is yet easily reproducable yet almost completely unguessable.

There are phone apps for hashing text using any of several different hash algorythms.

I'm a nerd, so stuff like this is pretty easy for you, but a little effort expended to obfuscate these kind of answers can go a long way towards ensuring your security from the casual hackers.
