Yeah, well, the problem is they're pushing more frequent password changes, while, according the the other admin I work with, NIST only
recommends
every two *years*. ESPECIALLY if you do *not* have single sign-on everywhere, frequent password changes, and required a lot of difference between the current password and the new one, *and* not coming anywhere near the last year or two's worth of passwords is worse than useless, it's counterproductive, since it makes social engineering much easier,
since
*everyone* will be writing down their passwords.

The whole 90 day password change recommendation came about because it was calculated to be the median number of days it would take to perform a brute password crack on a offline copy of the password hashes given a sufficiently complex password standard and a high-end desktop computer.
With Amazon's cloud services now I guess they'll have to cut it down to 7 days, or require finger print or retinal eye scans...
