Password Cracking - Questionnaire

For my MSc project I am looking at Password Cracking

This project looks at the following things:
  • How people generate passwords
  • What makes a secure password
  • What makes passwords memorable

For this project I am required to find out how people generate passwords.
To collect data I have created the following questionnaire and am asking people to fill it in.
I would be grateful if you could take a few minutes to fill it in.

As this deals with security and passwords, anonymity will be important to you.
For this reason no data which can identify you is collected and there is no way to connect any information you give about passwords to you as an individual.

Feel free to miss questions out if you do not wish to answer them.

1. How long are your passwords usually?

2. Which of the following do you use as a basis for your passwords?

Random word
A Name (Yours, Family member, Place, etc.)

3. Which of the following do you use to make up your passwords?

Nothing, just use the wordeg: cat
