numbers separated by a letter?
So, I was changing my account password with an online finance site, and they had many rules for the new password. Most of them made obvious sense ("You can't use your username in the password"). But one of the rules was "You can't have numbers separated by a letter." So "asdf7hjkl" is OK, but "asd6f7hjkl" isn't. Does anyone have any idea why? The only thing I can think of is that they're trying to make it harder to enter hexadecimal values or character escapes into the form. Any ideas?
