@ 2010/01/21
Imperva released a study analyzing 32 million passwords exposed in the Rockyou.com breach. The data provides a unique glimpse into the way that users select passwords and an opportunity to evaluate the true strength of these as a security mechanism.

The report identifies the most commonly used passwords:
1. 123456
2. 12345
3. 123456789
4. Password
5. iloveyou
6. princess
7. rockyou
8. 1234567
9. 12345678
10. abc123

123456789 is easy if you don't need security but the os requires a password to function properly.
Also very easy to enter on a laptop keyboard .

For enterprises, password insecurity can have serious consequences. “Employees using the same passwords on Facebook that they use in the workplace bring the possibility of compromising enterprise systems with insecure passwords, especially if they are using easy to crack passwords like ‘123456’,” said Shulman.
enterprise might have something like "password policies" which might now allow such easy passwords to be accepted
