After the security breach, database security firm Imperva analysed the passwords used, publishing a report entitled Consumer Password Worst Practices.

The data found that the most common passwords were:
1. 123456
2. 12345
3. 123456789
4. Password
5. iloveyou
6. princess
7. rockyou
8. 1234567
9. 12345678
10. abc123

Princess?? Really? What geek worth his salt uses princess as a password??

Princess?? Really? What geek worth his salt uses princess as a password??

My guess is that these are not "geek" passwords. These passwords are from the more 'simple minded', non-technical end users in systems. The probability that someone in a technically minded profession to use any of these is mind-numbingly minuscule. True "geeks" have a password template ingrained in their head from which they can deviate hundreds of thousands of complex passwords (or at least I do).

But I do have to say 5-7 are... interesting?
