It occurred to me that one of my online passwords was old enough that I really ought to change it, so I found the account-management page and went through the usual drill of “Current Password” “New Password” “New Password 2 Electric Boogaloo”.
I got a “password too short” error message. I was puzzled a moment, seeing how my new password was about a dozen characters long, until I noticed that it was complaining about the current password from back before the length rules were in place. 
After spending a moment trying to figure out how to get through a page that would reject my actual current password for being too short and would reject anything else for being too incorrect, I gave up and used the “forgot password - reset” link. :rolleyes:
