One of my pet peeves is stupid login or password restrictions. What it means is that for this login only, I have to use a different password. Some require you include numbers, some require numbers be between letters...
The stupidest one ever came up today. Blue Cross / Blue Shield requires:
Your password cannot contain the first three letters of a month (for example: Jan, Feb, Mar). Please try again. Thank you.
So if your password is Janet32puppy or imamartian, you're hosed?
